Implement FSM/Coordinator (still not functional)

This coordinator is based off of Ryan Zezeski's example FSM coordinator
in his working blog, try-try-try. Thanks to Ryan for all the work on
that.

Right now is this not functional.
Provided examples that are used for testing at the shell.
Implement shell script start/stop/setup/attach to cluster - butterknife, bk.
Almost! gen_fsm/coordinator is reaching 1 vnode, then timing out.
