adding standalone example
adding test for the standalone example

The test checks if the standalone/ directory can be copied and does
still compile (assumin that ./configure was run before and libMSSM was
created).
including . as first directory to enable local overwriting of headers
per convention distclean should remove the generated Makefile
removing .d on `make clean'
run `make distclean' in standalone/ sub-directory

Since the Makefile in the standalone/ sub-directory is not integrated
into the makefile module tree, we need to cd into the standalone/
sub-directory and run `make distclean' separately.

Note: standalone/Makefile is not included in the makefile module tree
by intention!  We want to provide a completely independent sub-package
with it's own Makefile.
