Improve testing of the codegen system

- Move codegen tests to a sub directory
- Add tests for all functions of Expression, ExpressionRef, and ExpressionGraph
- Respect dependencies during tests: The ExpressionGraph test doesn't
  use ExpressionRef anymore.

The new tests revealed a few bugs so the following changes were made:

- Expression::MakeNop now resets the current expression with the default
  constructed NOP expression
- ExpressionGraph::Insert now updates the lhs_id the same way as

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.
