%SOLVE Solve the expression

% This is the default solve that should be overloaded. Rearranges the
% equation e = exprptr.info to make the expression pointed to by ptr the
% subject of the equation.  No specific solve is defined, so leave the
% equation in the form e = exprptr.info  and return a problem to indicate
% that pexpr isn't the item pointed to by ptr.
