/*
?0 GUI NEURONMainPanel
	Main menu for standard control, graphing, menu generation.

	usage:
		load_proc("nrnmainmenu")
		nrnmainmenu()

	see grapher.hoc for how to use the grapher submenu item

	Serious users should peruse the init and run procedures.
	The run chain that eventually calls fadvance is
		run continuerun step advance fadvance
	There is often reason to substitute a new step or advance
	procedure to do intermediate calculations on the fly.
	Sometimes it is useful to replace the init() procedure. If so
	make sure you don't take away functionality which is already there.

? RealTime
	Running display of computation time. Resolution is 1 second.
? celsius
	Temperature
? AxialResistivity
	Assigns uniform value of Ra (ohm-cm) to all sections.
	Ra used to be a global variable but is now a Section variable that
	can be different in different sections. This sets Ra forall sections
	equal to the value displayed in the fieldeditor.
? RunControl
	Pops up a panel for controlling simulation runs.
?0 GUI NEURONMainPanel PointProcesses
?1 Managers
? PointManager
	Starts a general purpose PointProcessManager for specifying a
	location and defining what kind of point process should exist
	there. Any number of these managers can exist simultaneously.
	It is more general than the Electrode below in the sense that
	you can choose any point process and has a much cleaner
	implementation. See also: sections menu item
? Electrode
	Starts a general purpose voltage/current clamp (with some
	voltage clamp families) that can be moved to any postion in any
	section. Any number of these may be present simultaneously. When
	one is dismissed from the screen, it is also removed from the neuron
	and the point processes it manages are destroyed. See makeelectrode.
?1 Viewers
? PointProcesses
	Menu of possible pointprocess's. Selecting an item pops up a panel
	that contains a browser of the locations of a particular type of
	point process, and, if global parameters exist, a button for popping
	up a panel showing the global parameters for this type of point
	process. Double clicking a location on the browser pops up a panel
	showing the values for a particular point process instance.
?0 GUI NEURONMainPanel DistributedMechanisms
?1 Managers
? Inserter
	Starts an Inserter for the currently accessed section that
	allows one to insert and uninsert density membrane mechanisms.
	Currently this is most useful for single compartment simulations.
? HomogeneousSpec
	Starts a widget that is useful for specifing constant parameters for
	membrane mechanisms in all sections of a simulation. See
	makeshowmechanism.
?1 Viewers
? ShapeName
	Allows one to figure out the correspondence between the physical
	location of a section and a section name. Also allows one to
	get a parameter menu for the selected section.
? NameValues
	Pops up a panel for displaying values associated with Sections.
? MechanismsGlobals
	Menu of possible membrane Mechanism's. Selecting an item pops up
	a panel showing the global parameters for this type of Mechanism.

?0 GUI NEURONMainPanel
?1 NewGraph
	For creating common kinds of graphs of functions of time.
	These graphs are connected to the standard run procedure such
	that at every step (see RunControl) the value of the functions
	are plotted.
? Voltageaxis
	Plots values vs t.
	Suitable for plotting voltage and concentrations, especially when
	calculations are secondorder correct.
	v(.5) of currently selected section is always plotted but can
	be explictly removed with the Delete command in the Graph menu.
? Currentaxis
	Plots values vs t-.5dt
	Suitable for plotting ionic currents (when calculations are secondorder
	correct.
? Stateaxis
	Plots values vs t+.5dt
	Suitable for plotting states such as m_hh, n_hh, etc. These
	plots may be very accurate when secondorder = 2.
? Shapeplot
	Starts a PlotShape. A picture of a neuron suitable for specifying
	time, space, and shape plots.
? VectorMovie
	Starts a Graph that is flushed when above plots are flushed.
	This is suitable for selecting vectors from the PlotWhat menu
	and seeing them change every time step.
? PhasePlane
	Starts a Graph for plotting f(t) vs g(t). When started a dialog
	box pops up requesting the expression for g(t). As in the PlotWhat
	browser for graphs you may enter any variable or function, but it
	should change when the RunControl's InitRun button is pressed.
? Grapher
	Starts a widget for plotting any expression vs a specified
	independent variable. Lines are not drawn on this graph in
	response to a run. However it can be made to control a family
	of runs.
?1 Miscellaneous
	Several useful widgets for managing simulations.
? Family
	Starts a widget for controlling a family of simulations.
	One defines a variable and set of values for looping over an
	action.
? ParameterizedFunction
	Starts a widget for plotting a parameterized function and
	easily exploring its behaviour while varying the parameters.
	Also can fit the function to data using either the simplex
	or principal axis methods.

/*
?0 GUI RunControl
A minimal control system for managing a single "Oscillope sweep" level
simulation run. 

? t
Neuron time (ms). The field editor is updated regularly to display the
value of the global variable t.
? dt
	Value of the fundamental integration time step used by fadvance().
	When a value is entered into the field editor it is rounded down
	so that an integral multiple of fadvance's make up a SingleStep
? InitRun
	Initialize states, set t=0, and run the simulation until t == Tstop
	Plotting to graphs constructed from the NEURONMainPanel occurs at
	a rate given by the variable set by the Plotsms valueeditor.
	It is often convenient to substitute problem specific procedures
	for the default procedures init() and advance().
	The run call chain is
		run continuerun step advance fadvance
	The default advance is merely
		proc advance() {
			fadvance()
		}
	and is a good candidate for substition by a problem specific
	user routine.
	Warning: multiple presses of the this button without waiting
	for the previous simulation to finish (or pressing Stop) will
	execute the run() procedure recursively (probably not what is
	desired) Press the Stop button to unwrap these recursions.
? Init
	The default initialize procedure initializes states using
	finitialize(vinit) where vinit is displayed in the valueeditor.
	The init call chain is
		stdinit init (finitialize fcurrent)
	When more complicated initialization is required substitute a
	new procedure for the default init procedure:
		proc init() {
			finitialize(v_init)
			fcurrent()
		}
? Stop
	Stops the simulation at the end of a step. 
? Continuetil
	Continues integrating until t == value displayed in valueeditor.
	Plots occur each step.
? Continuefor
	Continues integrating for amount of time displayed in valueeditor.
	Plots occur each step.
? SingleStep
	Integrates one step and plots.
	A step is 1/(Plots/ms) milliseconds and consists of 1/dt/(Plots/ms)
	calls to fadvance()
? Tstop
	Stop time for InitRun
? Plotsms
	Number of integration steps per millisecond at which plots occur.
	Notice that reducing dt does not by itself increase the number
	of points plotted. If the the step is not an integral multiple of
	dt then dt is rounded down to the neares integral multiple.
