-/**
- * Notes for people who want to edit this file (not just use it as a library):
- *
- * Most of the interesting stuff happens in the derived classes of IdlObject,
- * especially IdlInterface.  The entry point for all IdlObjects is .test(),
- * which is called by IdlArray.test().  An IdlObject is conceptually just
- * "thing we want to run tests on", and an IdlArray is an array of IdlObjects
- * with some additional data thrown in.
- *
- * The object model is based on what WebIDLParser.js produces, which is in turn
- * based on its pegjs grammar.  If you want to figure out what properties an
- * object will have from WebIDLParser.js, the best way is to look at the
- * grammar:
- *
- *   https://github.com/darobin/webidl.js/blob/master/lib/grammar.peg
- *
- * So for instance:
- *
- *   // interface definition
- *   interface
- *       =   extAttrs:extendedAttributeList? S? "interface" S name:identifier w herit:ifInheritance? w "{" w mem:ifMember* w "}" w ";" w
- *           { return { type: "interface", name: name, inheritance: herit, members: mem, extAttrs: extAttrs }; }
- *
- * This means that an "interface" object will have a .type property equal to
- * the string "interface", a .name property equal to the identifier that the
- * parser found, an .inheritance property equal to either null or the result of
- * the "ifInheritance" production found elsewhere in the grammar, and so on.
- * After each grammatical production is a JavaScript function in curly braces
- * that gets called with suitable arguments and returns some JavaScript value.
- *
- * (Note that the version of WebIDLParser.js we use might sometimes be
- * out-of-date or forked.)
- *
- * The members and methods of the classes defined by this file are all at least
- * briefly documented, hopefully.

-     * Template code
-     *
-     * A template is just a javascript structure. An element is represented as:
-     *
-     * [tag_name, {attr_name:attr_value}, child1, child2]
-     *
-     * the children can either be strings (which act like text nodes), other templates or
-     * functions (see below)
-     *
-     * A text node is represented as
-     *
-     * ["{text}", value]
-     *
-     * String values have a simple substitution syntax; ${foo} represents a variable foo.
-     *
-     * It is possible to embed logic in templates by using a function in a place where a
-     * node would usually go. The function must either return part of a template or null.
-     *
-     * In cases where a set of nodes are required as output rather than a single node
-     * with children it is possible to just use a list
-     * [node1, node2, node3]
-     *
-     * Usage:
-     *
-     * render(template, substitutions) - take a template and an object mapping
-     * variable names to parameters and return either a DOM node or a list of DOM nodes
-     *
-     * substitute(template, substitutions) - take a template and variable mapping object,
-     * make the variable substitutions and return the substituted template
