Contributions summary:Marcin primarily focused on improvements to the Legion Parallel Programming System. Their contributions include optimizing build processes by changing how NVCC_FLAGS are expanded and implementing complex number support, along with improvements for half-precision floating-point numbers. They also updated the code to utilize Thrust with CUDA when Legion uses CUDA, switching to `std` complex otherwise. Minor corrections, such as fixing typos, were also part of the work.
