%-------function [edge,splitdata,lastbin] = EdgeCalculator(bin,start,stop,varargin)------------
%
% Calculate edge times/samples given a user-defined bin width and start/stop range.
% This is useful for things such as PSTHs, histograms, sliding averages,
% permuation entropy, etc. etc.
%
% >>> INPUTS >>>
% Required:
% bin = bin width (in samples)
% start = starting time (samples)
% stop = ending time (samples)
% Optional:
% Fs = sampling rate...useful for converting edge samples to time
% (put 0 as place holder if you want samples)
% data = data array (not matrix) to be split into segments
%
% <<< OUTPUTS <<<
% edge = edge times (in samples, seconds, or ms)
% splitdata = *optional* if input data array as optional argument,
% will split into segments of equal-sized/spaced data
% lastbin = if length(data) < stop, will find the next index
% from "edge" that can be used to parse the data (i.e. up
% to bin X).
