Updates include:
- std::move() cleanup in rcmatrix.h
- Enabled parallelization for fluid guiding (fairly noticeable speed improvement).
- More flexible flags setter function with control over boundary width.
Includes preprocessed Mantaflow source files for both OpenMP and TBB (if OpenMP is not present, TBB files will be used instead).
These files come directly from the Mantaflow repository. Future updates to the core fluid solver will take place by updating the files.
