%
% DESCRIPTION: STR2CELLS Take a single string and separate out individual
%              "elements" into a new cell array. Elements are defined as non-blank characters separated by
%              spaces.
%
%              Similar to str2cell, except str2cell requires an array of strings.
%              str2cells requires only 1 string.
%
% CALL:       newCell = str2cells(aString)
%
% INPUTS:     aString - string
%
% OUTPUTS:    newCell - cell array of strings
%
% EXAMPLE:    Consider the following string in the workspace:
%
% aString = ' a  b        c  d  efgh ij      klmnopqrs t u v w xyz    '
% newCell = 'a'
%           'b'
%           'c'
%           'd'
%           'efgh'
%           'ij'
%           'klmnopqrs'
%           't'
%           'u'
%           'v'
%           'w'
%           'xyz'
