This allows to accelerates a lot the evaluation of field defined in python as the conversion has to be done a limited amount of time. On The example-mesh-extraction-from-implicit.py exemple the computation time goes from 26 seconds with the current implementation using getValue down to 4 seconds with the getValues.

Currently the scalar field can be evaluated only one by one. This is very time consuming and not CUDA friendly. So I add a new method getValues to get a bunch of values in a single call.
Using the vector version accelerates a lot the the evaluation of fields especially when defined in python because the traversal from c++ to python has to be done one time.
A simple benchmark made on the file example-mesh-extraction-from-implicit.py.
It takes 26 seconds on my machine with the getValue API and only 4 seconds with the vector version.
