Move method candidate generation

[m-zakeri]

The problem
Currently, CodART uses JDeodorant to generate move method candidates.
The Python implementation of JDeodorant similarity algorithms is required for CodART.

Describe the solution you'd like
JDeodorant similarity algorithm [1] can be implemented using the ANTRL listeners.

Describe alternatives you've considered
Move method candidate can generate when detecting feature envy code smells as move method refactoring opportunities [2].

Prerequisite
