reduce an options object with alias keys
npm install aka-opts 
*
Dealias an options object. Tiny sugar topping that allows you to accept an options object full of aliases from your module users with aka-opts reducing that internally.
*
``
npm install --save aka-opts
*
` js
var dealias = require('aka-opts')
var opts = { frd: 36, zoo: 99, z: 9 }
var conf = { fraud: [ 'f', 'frd' ], zoo: [ 'z' ] }
opts = dealias(opts, conf)
console.log(opts)
// -> { fraud: 36, zoo: 99 }
`
*
Dealias options according to the mappings provided by conf which should look like:
` js`
{
originalKey: [ 'aliasKeyA', 'aliasKeyB' ]
}
Aliases are considered if options does not have the original key. dealias uses the first alias value it finds on options for the original key. dealias does not mutate options`. All alias properties are stripped off of the return object.
