[WIP] Move JSON/XML modules to separate projects

[mielientiev]

The main goal of this PR is to move JSON/XML modules to separate projects.

• remove Data module dependency from JSON modules
• remove Data module dependency from XML modules
• do cleanup
• fix most common XML/JSON bugs
  • XML: Cann't extract top level xml elements #262
  • XML: Wrong List serialization to XML #263
  • XML: Wrong extracting of XML list nodes #264
  • XML: Rapture Xml with optionals attributes #253
  • XML: Rapture Xml are not extractor for BigInt and BigDecimal #250
  • XML: Pattern matching on XML expressions is not working #247
  • XML/JSON: Problem with Serializers of case classes that contain Map[Int,Int] #238
• add more XML/JSON unit tests
• switch to contextual
• Move JSON/XML modules to separate repos

Just to confirm, regarding all the "new" code that is added, is that simply copy/pasted from rapture.data, then fixed to correct references to rapture.data?

I'm assuming that the deletions of the original files will be made after you've done the same thing with Rapture XML...

Anyhow, it looks good to continue now! Let me know if you need any help/explanations.

Is this red marking just GitHub's parser getting confused?

[mielientiev]

I think so. All code compiles and tests passes

[mielientiev]

@propensive Yep. For now, it's just copy-pasting from data module to json/xml module.
In future, all json/xml modules will only depend on rapture-core.
after I've done the same thing with Rapture XML, we can move Rapture JSON & XML to the separate repos

I'm going to tidy up Rapture, and keep track of this in Xylophone from now on.
