    + added new alternative BMDBFCDX implementation which respects RDD
      inheritance scheme and gives similar functionality and PRG functions
      as modified by Miguel Angel Marchuet <miguelangel@marchuet.net> DBFCDX
      with directly hardcoded bitmap filters.
      This code is completely new implementation and does not contain
      any code created by Miguel.
      This RDD inherits from DBFCDX so it's called BMDBFCDX anyhow
      it can inherit from any other RDDs so if users are interesting
      I can add also BMDBFNTX and BMDBFNSX.
      I haven't time of any deeper tests so please make them.
