Major changes include
* making convertion API context-sensitive
* the simplification of all the interfaces. The simplification is achived by applying IOC. Now AntEngine is responsible for creating and instantiating shared components via a ComponentManager.
* Moved most of startup code to AntEngine so that alternate front ends can be added in simply.
