joeduffy a2c376b9ed Implement the MuIL AST
This is an initial implementation of the MuIL AST.

The AST has been intentionally pared back to the bare essentials, leaving the
task of lowering to the higher level MetaMu compilers.  For example, there is
only a single conditional statement, a single looping construct, etc.

It is in the MuJS compiler package so that we can begin lowering TypeScript
ASTs to this format and serializing them.  We will need separate Go projections
of these shapes in order to deserialize and evaluate programs to produce MuGL
from within the runtime/evaluation engine.

I'm sure the shape of these things will need to change -- and there are a
handful of open questions -- however, this is a start...

Mu

Mu is a framework and toolset for creating reusable stacks of services.

Building and Testing

To build Mu, first clone it into a standard Go workspace:

$ mkdir -p $GOPATH/src/github.com/marapongo
$ git clone git@github.com:marapongo/mu $GOPATH/src/github.com/marapongo/mu

A good default value for GOPATH is ~/go.

Mu needs to know where to look for its runtime, library, etc. By default, it will look in /usr/local/mu, however you can override this with the MUPATH variable. Normally it's easiest just to create a symlink:

$ ln -s $GOPATH/src/github.com/marapongo/mu /usr/local/mu

There is one additional build-time dependency, golint, which can be installed using:

$ go get -u github.com/golang/lint/golint

And placed on your path by:

$ export PATH=$PATH:$GOPATH/bin

At this point you should be able to build and run tests from the root directory:

$ cd $GOPATH/src/github.com/marapongo/mu
$ make

This installs the mu binary into $GOPATH/bin, which may now be run provided make exited successfully.
