% FUNCTION: truncateCellArray
% 
% CALL: truncatedCellArray = truncateCellArray(cellArray, new_size)
% 
% The functions truncate the input cell array to the new_size, if no new
%     size is given the output cell array has the same length as the input
%     
% INPUTS:
%        cellArray    - cell array to truncate
%        new_size     - the new size of the cell array
% 
% OUTPUTS:
%         truncatedCellArray - the truncated cell array
