Vectorise evaluations in Python Expressions and SubDomains
Issue #904
new
Call-backs from C++ to user-defined Python functions for Expression
and SudDomain
are slow. It could be made much faster by supporting NumPy 'vectorisation'.
This shouldn't be very difficult once we've switched to pybind11 and using Eigen objects.
