translator changes...

[Ashok Hariharan]

Luca,

I have made some updates to the translator ....

-- the Translator interface now returns a hashmap with File handle
values instead of just a File handle (the map contains File handles to
both the ANxml file and the Metalex xml file)
-- the Translator has a usable REST interface (i am adding some
documentation shortly) configured using transformer.ini
-- Also added a Ant build.xml script with targets to create a jar
distribution, and also to be able to build the project without having
to install eclipse.
