function obj = cip_traceset_dataset(cts, cip_mags, dy, id, props)

% cip_traceset_dataset - Dataset of multiple cip magnitudes from cip_traces objects .
%
% Usage:
% obj = cip_traceset_dataset(cts, cip_mags, dy, id, props)
%
% Description:
%   This is a subclass of params_tests_dataset. Designed to extract a trace
% for each cip magnitude from the cip_traceset objects contained. Uses cip_traceset
% objects to extract multiple traces from each cip_traces object.
%
%   Parameters:
%	cts: Array or cell array of cip_traces objects.
%	cip_mags: An array of cip magnitudes to select from each cip_traces object.
%	dy: y-axis resolution, [V] or [A] (default = 1e-3).
%	id: An identification string.
%	props: A structure with any optional properties passed to cip_traceset.
%		
%   Returns a structure object with the following fields:
%	params_tests_dataset, cip_mags
%
% General operations on cip_traceset_dataset objects:
%   cip_traceset_dataset - Construct a new object.
%   params_tests_db - Loops over traceset objects and concatenates to form database
%
% Additional methods:
%	See methods('cip_traceset_dataset'), and 
%	    methods('params_tests_dataset').
%
