Physics

An extension module which optimizes common physics operators. The input tensors can be either polar or cartesian, however one needs to specify the source coordinate type explicitly using the Cartesian or Polar submodules. Similar to what was previously discussed, the inputs can be either combined or separate, depending on preference.
