*
* Filename: EntityConverter.hpp
*
* Description: Convert reflex entities to xonotic entities
* - Simple; operates on single entity at a time
* - Only context provided is information on what entities are related.
* (i.e. a teleport and it's destination) Can get this information
* through the pre-scan constructor of the .map file or by providing
* a queue of all the entities in the file.
* - Throws exceptions upon encountering malformed entities and when
* IO errors occur during object instantiation
*
* Version: 1.0
* Created: 05/27/2017 08:21:14 AM
* Revision: none
* Compiler: gcc
