Compile omni code into SuperCollider UGens.
Note that omni only supports nim version 1.6.0. It is recommended to install it via choosenim.
To install omnicollider, simply use the nimble package manager (it comes bundled with the nim installation).The command will also take care of installing omni:
nimble install omnicollider -y
omnicollider ~/.nimble/pkgs/omni-0.4.2/examples/OmniSaw.omni
