+ *
+ * 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,
