comments...
added the skel skeletons for modules and tests.  created outline for ceph then decided that's really not what I was trying to work on tonight...
first attempt at a "cluster" module...  unfortunately, I get an error.  there are two
commented lines after the actual method... I prefixed THEM with a space so hopefully git
doesn't actually ignore them...

wrote a test for it..  I'm not so sure I understand the numbering scheme of perl tests...
there needs to be a "renumber tests" tool...  write that down...

uhh... a.pl somehow made it into this commit.  just testing the results of ref.

root@kitt:~/Build-VM# perl t/01_build_vm_cluster.t
ok 1 - use Build::VM::Cluster;
Can't call method "count" on unblessed reference at lib/Build/VM/Cluster.pm line 47.
 # Tests were run but no plan was declared and done_testing() was not seen.
 # Looks like your test exited with 255 just after 1.
