/**
 * ### .addMethod (ctx, name, method)
 *
 * Adds a method to the prototype of an object.
 *
 *     utils.addMethod(chai.Assertion.prototype, 'foo', function (str) {
 *       var obj = utils.flag(this, 'object');
 *       new chai.Assertion(obj).to.be.equal(str);
 *     });
 *
 * Can also be accessed directly from `chai.Assertion`.
 *
 *     chai.Assertion.addMethod('foo', fn);
 *
 * Then can be used as any other assertion.
 *
 *     expect(fooStr).to.be.foo('bar');
 *
 * @param {Object} ctx object to which the method is added
 * @param {String} name of method to add
 * @param {Function} method function to be used for name
 * @namespace Utils
