% ----------[Lindex,Sindex] = findtrigs(trigger_chan,varargin)-------------
%
% Finds stim indexes from TTL stim channel given user-defined min/max
% thresholds for stims.
%
% >>> INPUTS >>>
% Required:
% trigger_chan: trigger data
% Optional:
% Lthresh: min, max for stim (i.e. [.2 .6])
% Fs: sampling rate...to return stim times in seconds
% mpd: minimum distance between peaks in samples (default = 0)
%
% <<< OUTPUTS <<<
% StimOn: time (in samples) of stim
% StimOff: time (in samples) of off-times of stim
% StimIndex: indicies of stims found (useful if stim channel has
% multiplexed stimuli)
% StimThrsh: output thresh for stims (to use in loop if desired)
