Prepare the node (for parser use only). See the discussion at the start of SeExprNode.cpp for more info.

Some friendlier error suggestions

Default is to call prep on children (giving AnyType as desired type). If all children return valid types, returns NoneType. Otherwise, returns ErrorType. Note: Ignores wanted type.
