The decision was to go with a pure OO design and thus use a dictionary 
for passing variable argument lists. If this will be a bottleneck or 
overhead we can change it easily afterwards. But I am not lucky with 
this current API, it looks to heavy weight, what do you think (to be 
consequent even the numVerts in the above example should be part of the 
params dictionary...)?
