## API
### Functions
Function | Description
------------------ | ------------------
`build/1` | Build a URI from a `uri()` or `url`.
`parse/1` | Parse a URI from a string, returning a `uri()`.
`parse/2` | Parse a URI, returning the result as either a `uri()` or `url()`.
`percent_decode/1` | Decode a percent encoded string value.
`percent_encode/1` | Percent encode a string value.
`plus_decode/1` | Decode a percent encoded string value that uses pluses for spaces.
