// Entity Templates
//
// Usage: These templates are used as the default values for entity properties.
//        Due to Pyrogenesis' data-inheritance model for these properties,
//			 templates specify a base-template, then override only those properties
//			 in that template that need to change.
//        Similarly, entities need only specify properties they possess that are
//           different to the ones in their respective templates. Of course,
//           properties such as position, current HP, etc. cannot be inherited from
//           a template in this way.
