    add tests for Composite sum(fractions)!=1.0

commit 7546fd7e761833c78b8d8730fa61ec437e4838b8

    fix composite sum of fractions

    Several things in the check if the fractions as positive and sum to
1.0
    were broken:

    - the normalization was never applied
    - if the sum was smaller than one, no warning was produced
    - 1.0-0.8-0.2 produces a negative number, but should be legal

    rework debug_print

    Material.debug_print was based on a current p, T given by the last
    set_state() and would return an unrolled list of minerals. This
makes it
    inconvenient to use and will provide the wrong information. Now it
will
    return a hierarchical representation independent of p,T. The old
    function is now available as print_minerals_of_current_state().

    improve mineral database documentation

    By not displaying all the inherited member functions, the mineral
    database help page becomes useful. This commit contains some cleanup
in
    the .py files. Most notably removing redundant comments mentioning
the
    source for the minerals.
