Simple javascript comparison of two objects with console logging/warning when different

compObj.js

/**
 * 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
