Merged elements of Versioner and AppDmgVersioner together.
Trying to figure out the copyright stuff at the beginning.
Renamed class to AppInfo to better reflect what it does.
Switched to using FoundationPlist. Working on handling all possible app_path input types.
AppInfo can now accept paths of a wide variety of types. Changed required path variable to info_path.
Cleanup.
Tests okay-arbitrary key access complete.
Renamed again to PlistReader
