+/**
+ * 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+ * out-of-date or forked.)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,
