/*
* 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
*
