minor change to test file
endomorphism height calculation, generic methods for images enumeration
changed MapperBinder to lambda function
total vertices num calculation for Endomorhpism
changed SkipMappedVerticesAcceptor class to lambda function
invertion of simple endomorphisms
Finished test of invertion, renamed EndomorphismSLP.slp() to image() and image() to image_word()
endomorphism conjugation
bug fixes, conjugation test
refactor bug fix in slp_reduce.cpp
Operator of equality and inequality for endomorphism
Now can change probabilities to generate inverter and multiplier
operator*= use std::bind now, free reduction uses cache of reduced vertices
