function N=parseCVDateType(string)
% Converts the date from a custom string format to Matlab's "serial date
% number"
%
% As of version 8db88227a3519800cb8968d8a51c3eb640f57b08 of the MindControl
% software, YAML data files are written with a date stamp in a particular format. 
% 
% For example:
%
% ExperimentTime: "Wed Jul 28 10:35:33 2010\n"
%
% This function parses that format.
%
% For the most up to date version of this software, see:
