* Breaks up the given `template` string into a tree of tokens. If the `tags`
* argument is given here it must be an array with two string values: the
* opening and closing tags used in the template (e.g. [ "<%", "%>" ]). Of
* course, the default is to use mustaches (i.e. mustache.tags).
*
* A token is an array with at least 4 elements. The first element is the
* mustache symbol that was used inside the tag, e.g. "#" or "&". If the tag
* did not contain a symbol (i.e. {{myValue}}) this element is "name". For
* all text that appears outside a symbol this element is "text".
*
* The second element of a token is its "value". For mustache tags this is
* whatever else was inside the tag besides the opening symbol. For text tokens
* this is the text itself.
*
* The third and fourth elements of the token are the start and end indices,
* respectively, of the token in the original template.
*
* Tokens that are the root node of a subtree contain two more elements: 1) an
* array of tokens in the subtree and 2) the index in the original template at
* which the closing tag for that section begins.
