function jpgFiles = getAllFilesjpg(dirName)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% getAllFiles grabs single file in a directory and all of its
% subdirectoris.  This function takes in just one argument, indir, which is
% the directory to search.
%
% SYNTAX:
%       getAllFiles(dirName)
%           indir = input directory to search through
%
% EXAMPLE:
%       files = getAllFiles('/home')
% This code was originally written by Kenneth Eaton, but revised to be used
% for the phenocam project.
