String to Cells

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.

Example: Consider the following string in the workspace:
aString = ' a b c d efgh ij klmnopqrs t u v w xyz '

>> newCell=str2cells(aString)'

newCell =

'a'
'b'
'c'
'd'
'efgh'
'ij'
'klmnopqrs'
't'
'u'
'v'
'w'
'xyz'
