Review request for MetaModel.
Bugs: METAMODEL-92
https://issues.apache.org/jira/browse/METAMODEL-92
Repository: metamodel
Description
-------
This patch makes it possible to specify column names with "paths" in
document-based data stores such as JSON files, MongoDB and CouchDB. The path
format is similar to that of EL/JavaScript syntax. It supports traversing maps
and lists/arrays. Here's an example of a few expressions:
* address.city
* addresses[0].city
* person.addresses[1].country.code
And so on...
I added the path based resolving method ("find(...)") to CollectionUtils -
seemed like the most appropriate place, and it makes it broadly reusable since
it is in the core module.

Testing
-------
Added unittests of path traversal (CollectionUtilsTest).
Added unittests for application to JSON files (JsonDataContextTest)
Added integration tests for MongoDB and CouchDB application
(MongoDbDataContextTest and CouchDbDataContextTest)
Thanks,
