## API

### `stringifyPosition(node|location|position)`

Stringify one position, a location (start and end positions), or
a node’s location.

###### Parameters

*   `node` ([`Node`][node])
    — Node whose `'position'` property to stringify
*   `location` ([`Location`][location])
    — Location whose `'start'` and `'end'` positions to stringify
*   `position` ([`Position`][position])
    — Location whose `'line'` and `'column'` to stringify

###### Returns

`string?` — A range `ls:cs-le:ce` (when given `node` or
`location`) or a point `l:c` (when given `position`), where `l` stands
for line, `c` for column, `s` for `start`, and `e` for
end.  `null` is returned if the given value is neither `node`,
`location`, nor `position`.
