Start adding Nek5000 example

Switch to include/ceed.h and lib/libceed.so directory structure

This gives the source directory a compatible directory layout with
the install directory, thus enabling a user to use either.

Add examples to test suite

Rename examples/ex1 -> examples/ex1-volume-annulus

examples/ex1: make -t (test) select smaller test case and print less

In examples/ex1.c, add parsing of command line options.

Trigger "make clean" in examples/ from the clean target in the main
Makefile.

In .gitignore, add Mac specific files to ignore.

Add file exam

In examples/ex1.c, set the mesh node coordinates using the appropriate
non-uniform spacing (Lobatto points) instead of uniform spacing.

Remove explicit linking with OCCA from examples/Makefile.

Fixing the build on my Linux box

Add examples/ex1.c which does not have external dependencies.

* By default, use order 2 space in ex3.cpp.
* Fix the description comments in ex3.cpp.

[occa] MFEM ex1 working

[occa] kRestrict kernel

Fix the MFEM example build plus a few other fixes and tweaks in the
OCCA backend.

Slight adjustments in mfem/ex1

CeedBasisCreateTensorH1Lagrange: change from degree to number of points

Simplifies calculation of sizes and will be compatible with other (e.g.,
non-polynomial or spline) bases.
