Add the expression return type as a member to Expression

Before this patch the return type was implicitly defined by the
ExpressionType. This patch separates this connection and allows
each Expression to have one of the predefined types (scalar,
boolean, void).

This patch is required to add support for the functions isfinite,
isinf, isnan, and isnormal. These are function taking a double and
returning a bool.

This also moves some complexity of the code generator to the
Expression, because the generator can direclty get the c++ type.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.
