%  function MMOut = reshapem(MMIn, newSize)
%
%  Works like 'reshape' but for multimatrices. The new indices are in a row 
%  vector 'newSize'. The first index is the "fastest loop" when shaping the new 
%  multimatrix.
%
%  MMOut, MMIn: MultimatrixT
%  newSize: Integer row vector with the new sizes of the dimensions.
