Expose bound methods

[thom4parisot]

Internal reorg of tldjs to look like more than a bunch of functions rather than a do-too-much-of-a-class.

import { getDomain } from 'tldjs';
getDomain(url)

Custom domains can be added by requesting a new instance of tldjs:

import tld from 'tldjs';

const customTld = tld.init(['localhost']);

fixes #86

That looks fresh and shiny! And it indeed solves the issue. I hope nobody minds the API change for customising rules and validHosts (please do remember to increase the major version number).

@Treora cool, thanks for your feedback :-)

I will certainly major bump before releasing. I need to tweak a few things before pushing the new version to npm.
