Encapsulation of libdc1394 initialization, handles, etc.
This class provides a wrapper around libdc1394's handles, camera nodes, bus initialization functions, and so on. It is implemented as a singleton so that any other part of Lobot/Robolocust can access it conveniently.
Ideally, this wouldn't be a singleton because there could be multiple FireWire buses on the host system. But for the purposes of the Robolocust project, this amount of abstraction is more than sufficient.

| void lobot::FireWireBus::release_camera_nodes | ( | ) | [inline] |
Camera nodes can be released after the camera devices have been initialized. This allows clients to free up memory associated with these nodes if they feel they won't set camera parameters (or call other functions that require the camera nodes) during the remainder of their lives.
NOTE: This method should not be called without due consideration has been given to the matter. That is: call it only if you're really sure you know what you're doing.
