Simple javascript comparison of two objects with console logging/warning when different
/**
* Compare versions of objects and warn of differences
* @param {object} v1 variant 1
* @param {object} v2 variant 2
* @param {bool} stringify optionally (if provided and `true`) stringify the variant parameters when dumping
* @param {string} root [internal use] nested key placeholder
* @example <caption>Example comparing two things:</caption>
* // should result in warnings for 'foo' and 'somebool'
* compObj({foo: "bar", id: 123, somebool: true}, {bar: "foo", id: 123, somebool: 'true'});
* @returns {void} nothing -- see console logging

function compObj(v1, v2, stringify, root) {
// only the stuff in the first version
for(var k in v1) if(v1.hasOwnProperty(k)) {

// wanna see the whole thing? how to dump...
