   All about PyPLN:    1) adding bool funtions-- @proved_by_brother_app and @proved_by_axiom to class Chainer.       adding  code to verify  above two conditions in Chainer.bc_step(), which prevent        backward chaining from proving one node in multiple ways and repeating the same proving       procedure many times.    2) adding head_dag(app) function    3) add a line in funtion @set_tv
