Easy to use

#### Module usage
``javascript
const abjs = require( 'ad-block-js' )
const client = abjs.create()

// curl -O https://easylist.to/easylist/easylist.txt
const easylist = require( 'fs' ).readFileSync( 'easylist.txt', 'utf8' )

easylist.split( '\r?\n' ).forEach( function ( rule ) {
client.add( rule )
} )

const url = 'example.com/foo/bar.gif'
console.log( client.matches( url ) ) // false

const adurl = 'example.com/foo/bar.gif&adflag='
console.log( client.matches( adurl ) ) // true
`

About

Parse a subset of url blocking rules in the ad-block rule format.

Why

Other alternatives are heavy and require gyp-rebuilds etc.

For who?

Those who want a simple but better than average ad-blocking.

How

Using plain JavaScript we parse some (not all) of the basic rule formats
and use primarily String.indexOf() to seek for matches ( indexOf
is an order of magnitude faster than traditional for-loops,
at least on V8 )
