VTKIO: Skip MONOMIAL variables as they cause crashes
Removed incorrect assert in equation_systems.C. Assert is no longer valid now that we can plot a subset of the systems in an EquationSystems object.
oops - did not complete enablegccdebugging -> enableglibcxxdebugging replacement.  done now
Merge pull request #5 from robert-we/master

Workaround crash when using MONOMIALs and VTKIO
warn rather than skip silently.
Don't double-add libmesh_*FLAGS when profiling
Misc example 2 needs a command line argument

This must have been stripped somehow during the transition to
automake, then not noticed because it's only active for
--enable-complex
update .gitignore
update .gitignore
slepc example ignores too
adding MeshfreeInterpolation class
adding InverseDistanceInterpolation & misc_ex8 to demonstrate usage
adding nanoflann as a contributed package.

nanoflann is a BSD-licensed C++ header-only library for building
KD-Trees, mostly optimized for 2D or 3D point clouds. Queries for
neighbors around any arbitrary location in space can then be solved
quickly and efficiently using Approximate Nearest Neighbor (ANN)
algorithms.

incorporating nanoflann into our build system
updating generated files from previous commit, separately so as not to bloat the diff
If we disable GLIBCXX debugging earlier on Darwin we can get it in the
AM_CONDITIONAL and do debug unit testing by default.
Merge branch 'master' into meshfree_interp
Updated InverseDistanceInterpolation class to use an internal KD-Tree.

This will need to be updated for the parallel case where we want to
allow for source data on remote processors - and I have an idea how to
do that - but I'm leaving that part for future work.
examples/miscellaneous/miscellaneous_ex8 demonstrates usage so far.

not actually interpolating yet.
Actually perform inverse distance interpolation.  Also interpolate two
different variables in the example to verify that functionality.
extend miscellaneous/miscellaneous_ex8 to do interpolation from one mesh to another
