%ROWMAP apply function to each row of array returning cell-array of answers
%
% rowmap(fn, A)
%   Apply function fn to each row of A and return all the
%   results in a cell array.
% 
% [a, b, ...] = rowmap(fn, A)
%   Apply function fn to each row of A. Output a is a cell array containing
%   all of the first outputs. Likewise b contains all of the second outputs.
% 
% ... = rowmap(fn, A, B, ...)
%   Now fn takes multiple arguments, taking a row from each of the input
%   arrays A, B, ...
%
% The returned cell array(s) are column-vectors in shape. If the outputs are row
% vectors and if fn only has one output, then cell2mat(rowmap(fn, A)) gives the
% same result as rowfun(fn, A).
