v2.0.1

This patch only updates the README, breaking out all object template documentation into a separate Object Templates API section.

v2.0.0

Breaking

• inverts isTemplate's logic and renames it to isNotTemplate, as isTemplate doesn't really determine whether a string really IS a template - it's only a heuristic.
• no longer throws on undefined variable access by default; instead makes all compiling API functions accept an additional options argument with a property throwOnUndefinedVariableAccess which if true will use the previous behaviour.
