Remove Transfuser Errata

[riastrad]

Per @colleenmcginnis's comment in mapbox/android-docs#639. This PR removes the code comments that were required to use the example-transfuser. Now that the docs are referencing submodules, those comments are no longer necessary and if anything would only be contributing needless noise to our code snippets.

Capturing chat with @riastrad - we no longer need transfuser when we're embedding the whole file with the new submodules approach (which makes it easier to keep the examples in sync). However, we'd still use transfuser for snippets in the docs where only certain parts of the code are required and including the whole file would be too noisy (e.g. location engine functionality, permission utils, plugins...).

Thanks @zugaldia. Spoke with @colleenmcginnis about this and just want to clarify the following point: currently /android-docs/ does not include any snippets that aren't full java files.

Tutorials and example code snippets on /help still rely on example-transfuser but are not pulled in from this repo. As a result, they are not affected by the transition to submodules.
