==== Spec

* Macros in skins are marked as (* *)(&42; &42;).
* Macros can contain both named and unnamed parameters, in any combination.
* Named parameters are denoted as name=value, unnamed parameters are denoted as value.
* For string parameter values, single or double quotes are optional unless the value contains whitespace characters.
* Macro parameters wrapped in ( ) are interpreted as nested macros.
* Macro parameters wrappedn in {{ }} are interpreted as nested skins.
* Skins and macros are both implemented as plain JS objects.
* Macro parameters are passed in a way that allows sequential value lookup, sequential name lookup and named lookup:
    var params = {
      values: [],
      names: [],
      byName: {}
* Nested skins and macros are passed to macros as skin and macro objects, respectively. In other words, macro evaluation and skin rendering is up to the containing macro.
* Standard macros such as if/else, foreach, equals, greaterThan are implemented as plain macros in JS.
