New MPAndroidChart v3.0b

• Elimination of the "x-index" concept (each Entry now has a float x- and y-coordinate)
• Change of the Entry constructor from Entry(float y, int xIndex) to Entry(float x, float y)
• XAxis and YAxis concept is now similar (XAxis no longer represented by Strings)
• Separation of the Realm.io support to a separate repository
• Bugfixes and stability improvement
• Many more...

Currently, the documentation is not up to date and still refers to versions prior to 3.0 - please have a look a the example project to figure out how the new API works. An update of the docs will follow soon.

Please also note that this is a "beta" release that might contain bugs that require fixing. A stable release 3.0 will be out within the next few weeks. If you are certain that you discovered a new issue with this new version, please let me know.
