- rename an element if its name is a reserved word or is shorter than 3 characters
- new names are built according to a simple pattern: (class|method|field)_<consecutive unique number>
You can overwrite this rules by providing your own implementation of the 4 key methods invoked by the decompiler while renaming. Simply
pass a class that implements de.fernflower.main.extern.IIdentifierRenamer in the option 'urc' (e.g. -urc=com.mypackage.MyRenamer) to
Fernflower. The class must be available on the application classpath.

(e.g. -urc=com.mypackage.MyRenamer) to Fernflower. The class must be available on the application classpath.
The meaning of each method should be clear from naming: toBeRenamed determine whether the element will be renamed, while the other three
provide new names for classes, methods and fields respectively.
