The 'assets.nix' file contains nix expressions that are a mutually 
recursive set of attributes used to create static asset directories 
with hashable file encodings. This file should be incorporated within
your project's 'default.nix' file. (See ./example/default.nix , line 2)
```
{assets ? import ./../assets.nix { inherit nixpkgs; }
}:
```

The 'mkAssets' and 'mkAssetsWith' functions within 'assets.nix' only
need to be passed an encoding('zopfliEncodings', 'gzipEncodings', 
'noEncodings') and a static directory of your choice as arguments.

In this example, 'mkAssets' is used on a directory that has a .png 
file inside of it. (See ./example/default.nix, line 11)
```
myAssets = assets.mkAssets ./static; 
```

Once you have successfully incorporated 'assets.nix' into your 
project's nix file(s), use nix-build to generate a symlink of 
your 'mkAssets' expression. The following command from 
example/run-example (line 3) will generate an immutable symlink 
that holds hashed static assets. 
```bash
nix-build -o static.assets -A myAssets
```
