CustomProgressBar

This PR consist in:

* Custom `GoogleProgressBar` that can be use directly form the XML layout.
* `attr.xml` file for the `GoogleProgressBar` to be set directly from the xml.
* `FoldingCirclesDrawable` `Builder`
* `gradle.build` file dependencies remove from library module
* `AndroidManifest.xml` refactor to remove code not needed in library module 
The `Builder` will make the #6 easier to be accomplish.
