%Usage: \makealiasesforwith\<mathcommand>{<prefix>}{<Set of letters>}
% to declare commands of form \<prefix><Letter> as \<mathcommand>{<Letter>} for each
% of the specfied letters
%
% E.g. \makealiasesforwith\mathcal{c}{ABC} will declare
% \cA \cB \cC \cD as \mathcal{A}, \mathcal{B}, \mathcal{C}
% This is also ensuring math context, so that
% \cA will be valid even in normal text.
