insensitive

Make sure anything you are working with becomes lowercase alphanumeric characters:

``js
import insensitive from 'insensitive';

const obj = insensitive();
console.log(obj.hello); // undefined
obj.heL_Lo = 'world';
console.log(obj.hello); // 'world'
obj.hello = 'bye';
console.log(obj.hello); // 'bye'

for (let key in obj) {
console.log(key); // 'hello'
}
Object.keys(obj); // ['hello']
