 Creates a clone of `value`. If `deep` is `true`, all nested objects will also be cloned, otherwise they will be assigned by reference. Functions and DOM nodes are **not** cloned. The enumerable properties of `arguments` objects and objects created by constructors other than `Object` are cloned to plain `Object` objects.  Note: Lo-Dash's deep clone functionality is loosely based on the structured clone algorithm. See http://www.w3.org/TR/html5/common-dom-interfaces.html#internal-structured-cloning-algorithm.

 A micro-templating method that handles arbitrary delimiters, preserves whitespace, and correctly escapes quotes within interpolated code.  Note: In the development build `_.template` utilizes sourceURLs for easier debugging. See http://www.html5rocks.com/en/tutorials/developertools/sourcemaps/#toc-sourceurl  Note: Lo-Dash may be used in Chrome extensions by either creating a `lodash csp` build and avoiding `_.template` use, or loading Lo-Dash in a sandboxed page.
