The Row implementation has no been replaced by RowVector and ReducedRowVector. A RowVector is an array of ArithVar and Rational pairs. (This replaces a map based implementation in Row.) ReducedRowVector is a RowVector with a notion of having a basic variable. The Tableau is now a collection of ReduceRowVector's. A major difference between ReducedRowVectors and Rows is that the iterator now includes the basic variable and its coefficient (always -1). Before only nonbasic members were accessible by the iterator.

Merge from cc-memout branch. Here are the main points
* Add ContextMemoryAllocator<T> allocator type, conforming to
STL allocator requirements.
* Extend the CDList<> template to take an allocator (defaults
to std::allocator<T>).
* Add a specialized version of the CDList<> template (in
src/context/cdlist_context_memory.h) that allocates a list
in segments, in context memory.
* Add "forward" headers -- cdlist_forward.h, cdmap_forward.h,
and cdset_forward.h. Use these in public headers, and other
places where you don't need the full header (just the
forward-declaration). These types justify their own header
(instead of just forward-declaring yourself), because they
are complex templated types, with default template parameters,
specializations, etc.
* theory_engine.h no longer depends on individual theory headers.
(Instead it forward-declares Theory implementations.) This is
especially important now that theory .cpp files depend on
TheoryEngine (to implement Theory::getValue()). Previously,
any modification to any theory header file required *all*
theories, and the engine, to be completely rebuilt.
* Support memory cleanup for nontrivial CONSTANT kinds. This
resolves an issue with arithmetic where memory leaked for
each distinct Rational or Integer that was wrapped in a Node.
