// This is a Metal implementation of subgroupPartitionNV. You use it to find a mask of
// the other threads in a simd-group with the same value (a partition of the simd-group about
// a set of values). 
//
// Feel free to use this in your code. Please share any fixes or ideas to make it faster.

Interesting libraries I might like to use in a project...

Asset loading:
	assetsys.h - virtual filesystem with ZIP backing, overlaying, etc https://github.com/mattiasgustavsson/libs/blob/master/docs/assetsys.md
	cute_filewatch.h - file modification watching, for runtime reloading etc https://github.com/RandyGaul/cute_headers/blob/master/cute_filewatch.h
	flatbuffers - data serialization, zero-copy deserialization, extensible schemas https://github.com/google/flatbuffers
	stb_image - https://github.com/nothings/stb/blob/master/stb_image.h
	tinyexr - https://github.com/syoyo/tinyexr

Exports Issues from a specified repository to a CSV and/or JSON file

Uses basic authentication (Github username + password) to retrieve Issues
from a repository that username has access to. If a public repository,
no user/password needs to be provided. Supports Github API v3.
Orginally based on a script by Brian Luft at https://gist.github.com/unbracketed/3380407

This requires installing the 'requests' package (https://pypi.python.org/pypi/requests/).

abs(x*a) = if (a >= 0) abs(x)*a

// basically any commutative operation
min(x,y) + max(x,y) = x + y
