Refactor UpdateTree() to pass parent bounds.
...
This is a little bit tighter, I think, and is necessary for cover trees, where the MaxDistance() to a node is not necessarily bounded above by the MaxDistance() to the node's parent.

Replace unsupported array operation with arma::vec

Dynamic length arrays are a g++ extension and their initialization is
only supported from g++-4.9.

Optimize small things in density estimation trees
...
While doing other work, I noticed a few things that could use
improvement:
* An std::vector that is used as an array
* Unnecessary dynamic memory allocation
I fixed these things and measured a marginal speedup.

Add OpenMP support to density estimation tree code
...
There are two parts to the OpenMP support. First, cmake was instructed
to compile with compiler-appropriate OpenMP flags. Second, three OpenMP
pragmas were added to dt_utils.cpp to parallelize the cross-validation
loop. No non-pragma code changes were necessary.

When BinarySpaceTree was refactored, its traits were not.

And thus the traits didn't work unless you were using the default SplitType.

Refactor to use BoundTraits. Remove nextDimension.
...
The extra overhead of tracking the number of tied dimensions is overkill, when that situation will happen so infrequently in practice. It used to happen with the BallBound where all dimensions are always the same, but the BoundTraits solution is better.
