Chain manager bug fixes & enhancment (more...)
...
* Set max length of a chain at -define(MAX_CHAIN_LENGTH, 64).
* Perturb tick sleep time of each manager
* If a chain manager L has zero members in its chain, and then its local
public projection store (authored by some remote author R) has a projection
that contains L, then adopt R's projection and start humming consensus.
* Handle "cross-talk" across projection stores, when chain membership
is changed administratively, e.g. chain was [a,b,c] then changed to merely
[a], but that change only happens on a. Servers b & c continue to use
stale projections and scribble their projection suggestions to a, causing
it to flap.
What's really cool about the flapping handling is that it *works*. I
wasn't thinking about this scenario when designing the flapping logic, but
it's really nifty that this extra scenario causes a to flap and then a's
inner projection remains stable, yay!
* Add complaints when "cross-talk" is observed.
* Fix flapping sleep time throttle.
* Fix bug in the machi_projection_store.erl's bookkeeping of the
max epoch number when flapping.

Add machi_flu_psup.erl to supervise all 3 FLU processes (see below)
...
Introduce machi_flu_psup:start_flu_package/4 as a way to start all
related FLU processes
* The projection store
* The chain manager
* The FLU itself
... as well as linked processes.
http://www.snookles.com/scotttmp/flu-tree-20150430.png shows one FLU
running, "a". The process registered "a" is the append server,
"some-prefix" for the sequencer & writer for the current <<"some-prefix">>
file, and a process each for 3 active TCP connections to that FLU.
