The variable scope in the Go templates makes it hard, if possible at all, to write templates with counter variables or similar state. This commit fixes that by adding a writable context to Node, backed by a map: Scratch. This context has three methods, Get, Set and Add. The Add is tailored for counter variables, but can be used for any built-in numeric values or strings.
