Added 1D Laplace solve for some tpetra/belos practice
Added laplaceEigs.cpp, practice for working with Anasazi objects.
Updated CMakeLists to include this test.
Added class which creates the linear operators and builds a BasicEigenproblem
for solving k-eigenvalue diffusion equation. Also added unit tests for this
class, and updated CMakeLists to compile these.
Added the InverseDiffusionOperator implementation of the Tpetra_Operator in order
to add functionality to EigenproblemBuilder to return a standard eigenproblem.
Updated the unit tests to compare restults from the standard eigenproblem against
the generalized eigenproblem.
I don't know... made a lot of edits and added the test which implements our simple
model for coupled fuel temp/neutron diffusion, as well as all of the functions
needed to implement that.
