% Finds all subdirectories in a given root directory, removes any
% directories with 'svn', and adds them to the Matlab path.
%
% Typically, it is a good idea to call this function in the startup.m file 
% which should be located somewhere along the default Matlab path. 
% ex: ..\My Documents\MATLAB\startup.m
% 
% Here's an example of what to include in startup.m:
%    addpath('C:\gits\epsych');
%    epsych_startup;
% 
% Alternatively, call this function only after retrieving software updates
% using SVN.
%
% Use a period '.' as the first character in a directory name to hide it
% from being added to the Matlab path.  Ex: C:\MATLAB\work\epsych\.RPvds
% 
% Default rootdir is wherever this function lives.
