Initial commit for a particle specific load balancer.

This load balancer is attempting to address performance issues in the DLB associated with particles.

In particular, the DLB balances on a single cost metric which is a function of the number of particles
and cells. This load balancer seperates the metric and load balances in two phases. During the first
phase any patches that have particles are assigned to processors and in the second phase all remaining patches
are assigned to processors. During the first phase the load balancer attemptes to equalize the number of particles
on each processor. The second phase then load balances the remaining processors while attempting to equalize
the number of cells on each processor, this is done while mainting the assignments from the first phase.

Theoretically this will help avoid synchronization problems associated with having varying numbers of particles
on each processor.

findNeighboringPatches()

- no longer using coarse/fine interface face iterator to determine if a patch is a
neighbor. Now returning ALL patches in the adjacent fine or coarse level. I wish there was a more efficient
algorithm but there isn't.

Moved the logic which removes particles that are not within the query range withing the query. Also save the results after removing those particles back into the database so future queries are faster.

BoundaryConditions.*:
Standard Arches inlets can now be named.
Inlet area is printed out with name when case starts up.
Also allow one to set the second mixture fraction in the old ARCHES bc. This is needed for property evaluation and should be fixed at some point when the old property evaluator goes away.

InletStream.cc:
Initializing second mixture fraction.

ExplicitSolver.cc
Tweaks on the scalar solver solve. i
Because of the multiple density issue and the generally bad abstraction of how density is handled, the scalar eqn needs to use tempDensity to stand in for the previous rk density for the FE update.

ScalarEqn.cc
Changes in which density is used.
Turns out Arches is copying density from old_dw->new_dw at the beginning of each time step so old_dw density was never needed.
Also need to use tempDensity for the explicit update.
Finally, needed to change the "evalTransportEqn" to check if the equation used density guess to be able to handle density abstraction (see update to ExplicitSolver.cc).

arches_ups.xml
Update spec to allow for naming of inlet and adding mixture_fraction_2 value or <FlowInlet>.

First of a couple changes to how particle subsets are stored.

This removes the low and high index from the map key and changes the map to a multimap. Queries now search this multimap and then linearlly search the resulting entries (should be between 1-7 entries) for a sufficient match.

This eliminates linear searches through the entire particle subset database in order to find a sufficient match.

1) Density should not be treated differently on boundaries. Now always interpolated with 2nd order interpolant.
2) Because of 1), there is no longer a need to have a special getDensityOnFace function.
3) Indexing was incorrect on construting the Boundary face iterator.

Add the ability to call getModifiable(gridVar) with ghost cells. Users should be able to write to these ghost cells but any data written to them will be lost when the task exits. This is useful for computing data locally instead of communicating it (for example a node entered value that is computed from a cell value which is required with ghost cells).

Change the logic for determining the range that particles exist within.

Previously the computation was done using two different methods.

The first method mapped
the particle position to a cell index and then compared that index to the low and high indices.

The second method would map the low an dhigh indices to a position and then compare it to the
particle position.

In very rare cases these would not give the same answers due to floating point error causing
a critical failure.

We now use exclusively the first method for this calculation.

Added a static member containsIndex(low,high,idx).

This is useful for doing a patch intersection when you don't actually have a patch. I have also utilized this function throughout the patch class in order to reduce code duplication.
