Added 4-particle vecangle potential; untested, and configuration.cpp still needs to build the potential dictionary using type,filename tuples as keys

This reverts commit c6c19c64, reversing
changes made to c195bf09.

Initial port to cuda11: include c++14 std, use texture objects instead of deprecated texture refs, squash warnings

Added 4-particle vecangle potential; untested, and configuration.cpp still needs to build the potential dictionary using type,filename tuples as keys

Fixed bugs in initialization of Exclusions and in the calculation of forces due to angle potentials . Added coordinate file for RBs. Added normalization of orientation in RB integrator.

computeTabulateBonds works, bug computing forces fixed, bondList is created, but not implemented yet.
