 * (https://github.com/olado/doT).
 *
 * This version differs from lodash by removing support from ES6 quasi-literals, and making the
 * code slightly simpler to follow. It also does not depend on any third party, which is nice.
 *
 * Finally, it supports SourceMap, if you ever need to debug, which is super nice.
