proposed Lorito roadmap

This roadmap proposes that Lorito be planned and implemented over the course of four stages.  The tasks within a 
stage should be more of less independent of each other, making division of labor easier for interested developers.

stage 0: prep
 * get an nqp-rx-based ops compiler ("opsc") generating similar C code to ops2c
 * check in generated C code for ops and PMCs for bootstrapping
 * define Lorito ops and semantics (ffi, arg format, binary format, registers, ops, syscalls, text format, etc)
 * implement some PMCs, ops and library bindings/PMCs in Lorito to demonstrate that Lorito is sufficiently powerful

New in 2.2.0
- Core changes
- API Changes
- Platforms
  + ICC and Sun cc support have been restored
- Tools
  + Makefiles now invoke the compiler directly rather than going through a Perl script
  + NCI thunks are now generated by PIR code

#Note: none of the classes are implemented.  This is just to figure out what kind of interface will be reasonable.

my $pir_code :=
'.sub main
  say "what"
.end';

my $prof := ProfTest;PirProfile.new($pir);

#Does the profile have a version string?

This is a rough draft proposal for a timeline to migrate Parrot from our current svn repository over to parrot/parrot github.

Prereqs:
* nobody is strongly opposed to using github
* github plugin is complete and well tested
* workflow and branching/merging docs are updated
* make sure everyone who has committed anything recently has a commit bit on github


approximate timeline:

MOP topics:
  What is a MOP?
    - a MOP is a programmatic interface for creating classes.
    - in our case, it's split into REPR (low-level representation) and HOW (other)
    - 
  What is our MOP?
    - It's based on jnthn's 6model work.  Go read up on that now.
    - his timeline is uncertain, but this is worth getting right
      - Rakudo needs it and he's capable.  We'll wait.
