- This update adds DynamicArray<T>. This is a bare bones heap allocated array that dynamically can increase in size. This has functionality similar to vector<T>. The main difference is that it can be constructed in an ill-formed manner. This means that it can generalize CDList<T>.
- CDVector<T> has been added. This is intended to allow for context-dependent destructive updates, while the vector size increases are permanent. Behaviorally, this is most similar to vector< CDO<T> >. The differences between the two are: only one ContextObj is registered to the Context, backtracks are done in a lazy fashion, CDVector::push_back(val) sets the value of back() at context level 0 to val where vector<CDO<T>>::push_back(val) sets back() at the current context level to val and back() at context level 0 to the default constructor T().

"Leftist NodeBuilders" are now supported.
That is, "nb << a << b << c << OR << d << AND" turns into
(AND (OR a b c) d)
The rule is: pushing a kind onto a NodeBuilder with a nonzero
number of child Nodes in it, the action "collapses" it. If a
kind is already associated to the NodeBuilder, it is an error.
Thus:
NodeBuilder<> nb(AND); nb << AND;
and
NodeBuilder<> nb; nb << AND << OR;
are both errors (if assertions are on).
In reality, though, the implementation is trickier, as the collapsing
is done lazily on the following push. This complicates things a bit,
but by placing an Assert(false), I found that we aren't depending on
the old behavior (at least for any unit tests or regressions in the
source tree). The Assert(false) is now removed and leftist
NodeBuilders are in business.
