# Function: OnPrototypeEnd

# type - The <TopicType> of the prototype.

# prototypeRef - A reference to the prototype so far, minus the ender in dispute.

# ender - The ender symbol.

# ENDER_ACCEPT - The ender is accepted and the prototype is finished.

# also continue on so continue parsing. If there is no accepted ender between here and
|
||
|
|
# the end of the code this version will be accepted instead.
