# The BaseBinding class is the base for all bindings. It takes
# 4 arguments that should be passed up from the children (via super)
#
# 1. page - this class instance should provide:
# - a #templates methods that returns a hash for templates
# - an #events methods that returns an instance of DocumentEvents
# 2. target - an DomTarget or AttributeTarget
# 3. context - the context object the binding will be evaluated in
# 4. binding_name - the id for the comment (or id for attributes) where the
# binding will be inserted.
