      (1) Taskadmin renamed as liomain; since it is going to be called
          directly by outside programs like amber, it might as well have
          the name of the program in it.

      (2) Liomain is called by both liosolo and SCF_in, but still does
          nothing (it is empty of commands). The idea would be to
          eventually replace SCF_in by liomain and another interface
          subroutine that passes the information from amber to lio
          (liosolo would be doing the information gathering but from
          input files instead of "translating" amber data, and then
          it would call liomain).
