Cell Array Mimic

CAindex mimics a cell array by overloading the following functions,

'CAindex'
'ctranspose'
'disp'
'end'
'horzcat'
'numel'
'plot'
'size'
'subsasgn'
'subsref'
'transpose'
'vertcat'

The attached test file illustrates the different operations it can perform. The way it differs from a normal cell array is that I can call it like this,

C('ColumnTitle')

which is the same as

CELLARRAY(:,x)

if the element in CELLARRAY(1,x) is 'ColumnTitle'

Also,

C{'FirstColumnTitle'}

works similarly.

This was motivated by the desire to mimic a cell array with only subtle differences which is one of the more challenging things to do with MATLAB classes.
