using geom class

- dropped the use of the material class as it does not allow to have
empty phase and crystallite. The material.config class needs a severe
refurbishing (no crystallite, use orderedDict instead of hand written
solution, drop of texture components). Probably best solution is to
postpone this until we have a yaml/json reader for Fortran.
