 * Builds proxy functions on the `to` object which pass through to the `from` object.
 *
 * For each key in `fnNames`, creates a proxy function on the `to` object.
 * The proxy function calls the real function on the `from` object.
 *
 *
 * #### Example:
 * This example creates an new class instance whose functions are prebound to the new'd object.
 * ```js
 * class Foo {
 *   constructor(data) {
 *     // Binds all functions from Foo.prototype to 'this',
 *     // then copies them to 'this'
 *     bindFunctions(Foo.prototype, this, this);
 *     this.data = data;
 *   }
 *
 *   log() {
 *     console.log(this.data);
 *   }
 * }
 *
 * let myFoo = new Foo([1,2,3]);
 * var logit = myFoo.log;
 * logit(); // logs [1, 2, 3] from the myFoo 'this' instance
 * ```
 *
 * #### Example:
 * This example creates a bound version of a service function, and copies it to another object
 * ```
 *
 * var SomeService = {
 *   this.data = [3, 4, 5];
 *   this.log = function() {
 *     console.log(this.data);
 *   }
 * }
 *
 * // Constructor fn
 * function OtherThing() {
 *   // Binds all functions from SomeService to SomeService,
 *   // then copies them to 'this'
 *   bindFunctions(SomeService, this, SomeService);
 * }
 *
 * let myOtherThing = new OtherThing();
 * myOtherThing.log(); // logs [3, 4, 5] from SomeService's 'this'
 * ```
