Represent the Java AST with Famix

## Installation

To load the FAST-Java project, execute in a playground

```st
Metacello new
  githubUser: 'moosetechnology' project: 'FAST-JAVA' commitish: 'v3' path: 'src';
  baseline: 'FASTJava';
  load
```

If you want to load the SmaCC importer with the model (create a FAST Java model from string)

```st
Metacello new
  githubUser: 'moosetechnology' project: 'FAST-JAVA' commitish: 'v3' path: 'src';
  baseline: 'FASTJava';
  load: 'all'
```

## Create a FAST-Java Model based on java string

Thanks to the [Smacc Project](https://github.com/j-brant/SmaCC) it is easy to parse Java methods and classes.
We used a visitor on the parsed java string to create a FAST-Java model.

If you need to create a FAST-Java model from a method or class, the easiest way is thus to perform:

```st
JavaSmaCCProgramNodeImporterVisitor parseCodeMethodString: 'void hello() {
    // My method string
}'
```
