Basic scheme

Each simulation has a length determined by a very narrow (pinched)
diameter at dendrite length X microns from the soma which effectively
electrically ends the dendrite at this pinch.  For each of these X
distances there are vectors for the spatial profile of the maximum bAP
voltage as a function of distance along the dendrite:

max_bAP_ctrl_vec_X.txt
max_bAP_inhib_vec_X.txt

Another vector, distance.txt contains the distance for each
corresponding dendrite compartment (segment or node) in the above
envelope files.

A dendrite_length_vec stores the length of the dendrite for each
simulation as successive elements.

Spine Ca signal measurements:
dCa_inhib_vec.txt
dCa_ctrl_vec.txt
dCa_ratio_vec.txt
dendrite_length_vec.txt (associated with above)

Loop over (pinched) lengths of dendrite:

1) calculate control and inhibition bAP envelope's and Ca peaks and
baselines

2) store vectors in files in folder sealed_end
