Adding documentation to use a local copy of the OpenXC library

[rwoberholzer]

I've recently run into the issue of needing to use a local copy of the openxc-android library as a dependency. To do this, I added the following to settings.gradle in my app:

include ':library'
project(':library').projectDir = new File(settingsDir, '../openxc-android/library')

and replaced compile 'com.openxcplatform:library:6.1.6+' with compile project(':library') under dependencies in build.gradle.

@emarsman mentioned that it may be a good idea to include this in the OpenXC documentation in case this situation arises for other people.

If anyone knows of a better way to implement using a local dependency, please let me know.

You also need to add some dependencies and other info to build.gradle in the app you're creating. This is an example of what is needed: https://gist.github.com/rwoberholzer/f56cf8a8c209045ad6baca27a2581298

I updated the Android Library Installation and App Tutorial pages with instructions for using a local copy of the OpenXC Android Library. This required several files to be added to the starter app and the Enabler. There were 3 associated PRs that were approved and merged:
