Adding initial support for atomics in kokkos:
  T atomic_exchange(T* dest ,T val)
  T atomic_compare_exchange(T* dest ,T compare, T val)
  T atomic_fetch_add(T* dest ,T val)
T can be: 
  (unsigned) int, (unsigned) long int, 
  (unsigned) long long int, float, double
Implementation on the host side requires either Intel or GCC atomic
intrinsics or OpenMP 3.1. Intrinsics are prioritized, since they
generally give better performance. On the GPU CUDA intrinsics are used.
Atomic functions which are not directly supported (i.e. all functions
operating on double) are implemented using atomic_compare_exchange. 

Intel compatible atomic intrinsics should be available with Intel, GCC,
PGI, Cray and IBM compilers.
Adding Multivector prototype for KokkosArray based linear algebra
subpackage in Kokkos. 

Supports: 
  Dot product r=x*y, 
  Vector add r=a*x+b*y, 
  Scalar multiplication r=a*x;

Initial commit contains unit_test (for Scalar: int, long long, float
and double) and a performance test. Both can not be integrated in the
Trilinos unit test system at present (they are standalone executables).

Upgrading PyTrilinos compatibility with latest NumPy API

I have changed PyTrilinos code to directly use the new NumPy API, and
have used macros to redefine those symbols if we are using an older
version of NumPy.

My first attempt at testing, I enabled only Teuchos, Epetra and
PyTrilinos.  I am currently getting 4 unit test failures.  I need to
go back and determine whether these errors are due to my new
PyTrilinos changes, or other changes made by Epetra developers.
Epetra: Adding reverse distributor creation / extraction.

If it isn't a negative line checkin, it is close...
Epetra: Finishing Import/Export reverse constructors.

Tests also added.
Epetra/EpetraExt: Extending ESFC to allow for exporter specification.
Xpetra: EpetraCrsMatrix ESFC mods.

Exporters galore!
EpetraExt: Speeding up Transpose using fast Import/Export reverse constructors.

Turning off a couple of PyTrilinos unit tests

These are the ReplaceMap() method tests that are failing because of
some changes Chris Siefert made.  I just changed the method prefix
from "test" to "notest".  I can change them back when Chris addresses
the underlying problem.
Reinstated the NumPy_Backward_Compatibility fragment in numpy.i
Upgraded to be compatible with deprecated NumPY API

Also changed the indentation, which seemed to be all over the place.
Note that SWIG runs on this file and the resulting wrappers compile,
but I am getting several new SWIG warnings.
Epetra64:  Fix compilation errors that appear if either 32 bit
or 64 bit indices have been disabled.  Most of the changes are
due to checkins related to LowCommunicationMakeColMapAndReindex.
cast index_type to int for sprintf
MueLu: moved RAPFactory to new stack (with validParameterList)
MueLu: CoalesceDropFactory: fixed the conditions for Input of Coordinates
MueLu: updated Level::print() to include reqesting addresses
MueLu: always remove requesting factory during Release

For some reason, we checked the kept flag of the factory before we
erased the requesting factory during Release. We don't need to do that.
Panzer: Adding discrete adjoint capability to SG Epetra scatter

This was previously done for the Epetra scatter for deterministic adjoints.
Here we are enabling it for the stochastic adjoint systems.
Panzer: Adding IPCoordinates response builder

Done in support of VERA coupling tools. Also this code is easy to
include!

Also modified test to use new builder.
