This module shallow copies an object, ignoring keys depending on the filter object passed to it.
var someInput = { a: 1, b: 2, c: 3 }
// ...
var blacklist = require('blacklist')
blacklist(someInput, {
a: true, // a will not be in the result
b: false, // b will be in the result
c: 1 > 2 // false, therefore c will be in the result
})
// => { b: 2, c: 3 }
