Support multiple class types for language adaptors
changing package to rx.*
update language adaptors to rx.* package
Refactoring towards performance improvements

- Convert operators to implement Func1 instead of extend Observable
- Change Observable to concete instead of abstract
- subscribe is now controlled by the concrete class so we can control the wrapping of a Func to be executed when subscribe is called
- removed most wrapping inside operators with AtomicObservable except for complex operators like Zip that appear to still need it

While doing these changes the util/function packages got moved a little as well to make more sense for where the Atomic* classes should go
fixing compile issues after core refactoring
IDE support

Importing into Eclipse Juno with the Gradle plugin now gets everything setup, compiling and running correctly.
builds for each language and examples

Use 'provided' not 'compile' for language dependencies so we don't force specific versions.
removing .observables package so main classes are just rx.*
dependency management
Eclipse build config

- Include 'provided' in Eclipse classpath
- Upgrade to Groovy 2.+
migrate unit tests for Groovy to separate Groovy file

- testing all Groovy functionality doesn't belong as an inner class
- it was awkard to load Groovy scripts via Java (leftover from previous codebase where Groovy wasn't part of build, only a runtime library)
- establish convention for each language to have a suite of tests in /src/test
groovy example code

- examples are in /src/examples/groovy
Renamed takeWhile with Func2 parameter to takeWhileWithIndex

Added takeWhile and takeWhileWithIndex methods to Observable
Update language-adaptors/rxjava-groovy/README.md
Add IntelliJ Idea support to Gradle build
