example problem utilizing objects.

build script creates dummy include/ and src/ dirs

The MOOSE build script expects a couple of subdirectories in the app directory (include/base and src/).  These aren't available in the Nek+MOOSE example directories, so the MOOSE build script will throw some (harmless) warnings.  The changes to the build script will create empty include/base and src/ directories if those don't already exist.

Also add a new Multiapp coupling example
Finally rename NekTimestepper to NekTimeStepper

Added build script for coupled MOOSE+Nek5000 example

This includes a script (examples/template_example/build_coupled_nek.sh) for building the Nek5000 libraries and MOON.  The script also deletes/updates the Nek5000 configuration files.  

.gitignore is updated to include build and run artifacts from Nek5000.
