Pre-meeting Examples

These are the examples we have working prior to the meeting with INL.  They include:
* Heat conduction in a 2D circular and 3D cylindrical domain
* A "hello world" example to link Nek and MOOSE

See merge request !2

Test driver

This adds two top-level examples in `moon/examples`
* `ex01_inputfile` is the same as `moose/examples/ex01_inputfile` except the Makefile paths have been updated
* `hello_nek` is the same as `ex01_inputfile` except it compiles `libnek5000.a`, initializes Nek from `eddy_uv.rea` and prints some values from a common block.  After that, it runs `ex01` to completion.
