added a new module called numerics.f90 which reads in all numerical "parameters" from the file numerics.config (also being added). From now on this file has to be located in the working directory of the FEM-model and has to contain all necessary parameters.

numerics.config is now optional; if this file does not exist in the working directory, standard values from numerics.f90 are used; either way the output file tells which values were taken. added some output to the init subroutines of debug.f90, FEsolving.f90, lattice.f90, material.f90 and mesh.f90.
