Backward Compatibility with Version 6.3 and Earlier

Due to the changes in the structure of the Mixer Module Part Library, Java files using parts need to be updated. For example if a Rushton impeller was used, the line

model.geom().load(new String[]{"part1"}, "Mixer_Module\\Impellers,_Radial\\rushton_impeller.mph",
new String[]{"part1"});

should be replaced by

model.geom().load(new String[]{"part1"},"Mixer_Module\\
Impellers,_Surface_Blades\\Impellers,_Radial\\rushton_impeller.mph",
new String[]{"part1"});
