joeduffy 1ad99bcea1 Fix a few AST marshaling things
This fixes a few things so that MuPackages now unmarshal:

* Mark Module.Members as requiring "custom" decoding.  This is required
  because that's the first point in the tree that leverages polymorphism.
  Everything "above" this unmarshals just fine (e.g., package+modules).

* As such, stop marking Package.Modules as "custom".

* Add the Kind field to the Node.  Although we won't use this for type
  discrimination in the same way, since Go gives us RTTI on the structs,
  it is required for unmarshaling (to avoid "unrecognized fields" errors)
  and it's probably handy to have around for logging, messages, etc.

* Mark Position.Line and Column with "json" annotations so that they
  unmarshal correctly.

Mu

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

If you are learning about Mu for the first time, please see the overview document.

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.
