WIP: PlantUML and Markdown Export support

[MikeFot]

Massive WIP!!!

This is written as quickly and hardcoded as possible. Will get around to fixing it soooooooooon (famous last words).

Changes

• 2 new export types are supported: To PlantUML and to Markdown. A file will be generated for each class.

New CLI Parameters

• Added a -p [package_prefix] parameter for filtering a DexClass list by package name.
• No parameters added for toggling the 2 new exports (yet!).

Sample Usage

-h --input /some.apk -p com.alt234 -o /output/
