Lambda Day -> Lambda Month

Hello all,

So we announced Lambda Day rather prematurely.  I had not actually ran 
any of the lambdification tooling and once I did, I found that they all 
produce lamdified code with compile errors.  Most of the lamdified code 
works, but the odd lamdification does not.  Naively, we had assumed that 
we could flip a switch and walk away lambdified.  Silly us.

Now that we know code will need to be edited manually, we have decided 
to lambdify components one at a time over the next month or so to better 
allow us to control the process.  The first component to be lamdified is 
Samples, Mandelbrot and Ensemble8.  But wait, Mandelbrot was already 
lambdifed so no change there.

Since lamdification is such a pervasive change, we'll be announcing on 
the list when components are going to change and coordinating with the 
component owners.  The JIRA that is tracking the work is

The good news is that the lambda flood gates are open in all 
components.  The Android and iOS ports have agreed to use RetroLambda to 
keep their ports going.  Remember though, use of the streams API and 
other JDK8 library functionality like this will kill these ports so 
these features cannot be used in shared code.  In platform specific Java 
code, there is no issue.

I was so happy and then the wind was taken out of my sails. Software has 
let me down.
