Schema Parser for concrete syntax

[wisnesky]

TODO

• Choose a sensible syntax fragment to start with; maybe this one

  schema S = literal : Ty {
    entities
        Person
        Company
        CompanyPerson
    foreign_keys
        persons_id   : CompanyPerson -> Person
        companies_id : CompanyPerson -> Company
    attributes
        firstname lastname : Person  -> String
        name               : Company -> String
  }

There are two Java parsers in the original AQL repo; one is based on an ANTLR grammar, while the other is a Java parser combinator thing. See also https://github.com/babeloff/fql

@marcosh @wisnesky Shall we cut this up into sub-issues and rename this particular one to be about the schema parser? I think for all Marco's hard work, he's earned the privilege and satisfaction of getting to press 'close issue'. Also that would make things easier to track and subdivide.

Works for me
