function [x] = parse(inStr)
% parse is a function which takes in a string vector of blank separated text
% and parses out the individual string items into a n item matrix, one row
% for each string.
%
% function [x] = parse(inStr)
% x     - the return matrix of strings
% inStr - the blank separated string vector
