A simple syntax for remapping objects, inspired by several of Ramda's spec based functions

 * A port of [Ramda's evolve()](http://ramdajs.com/docs/#evolve), but the transforms are _always_ applied regardless if the key/value pair exists in the input object or not.

 * @param {Object} input The input object to pass through prop-level transformations
 * @returns {Object} The modified input object, with any prop-level transforms applied to it
