Feature Request - isLatLong(lat-long-pair)

[roydondsouza]

Support for isLatLong:

var validator = require('validator');
validator.isLatLong('12.0122,-77.00'); => true

var validator = require('validator');
validator.isLatLong('-200.0122,-77.00'); => false

Libraries that currently validate and return lat,long coordinate pairs:
@markstos has forked to-coordinates [that was lacking stricter parsing which he has raised in the issue here: Wish: stricter parsing of lat/long coordinates pairs #2] to create a stricter parsing of lat/long pairs in a wonderful library called parse-coordinates

We could use this to support - isLatLong('12.0122,-77.00') within this library.

If I were to put something together for a PR, do you support reuse of parse-coordinates as a dependency here or write the entire code here?

[markstos]

parse-coordinates already works directly as a validator because a coordinate array casts to a "true" boolean value, while the null returned on a parsing value casts to a "false" boolean value.

The value of adding it to or validator.js would be that it is more convenient to find.

@markstos thanks for replying. Yes, that was the intention; to use it as an internal dependency within validator.js and make it available for convenience
