/// This method initializes the context. It is assumed that this would be done once on the
/// beginning of the game. Note that this is called on the singleton so multiple initializations
/// will simply do nothing (which might cause problems with other objects). If for some reason a new
/// initialization is needed, the @ref Dispose method should be called first (however ALL
/// other initializations will be required first such as reinitializing the nodes). Also, it is assumed that
/// every node created externally using the @ref CreateNode method will be released (using the @ref ReleaseNode
/// method) BEFORE releasing the context.
/// @param logger the logger object we will enter logs into
/// @param query A query limiting the nodes found.
/// @param xmlFileName this will hold an xml file to initialize from. A null or empty filename
/// will simply be ignored and the object will be built without it. An illegal filename will cause
/// an exception!
/// @param recordingFilename This holds the filename for playing a recording.
/// @ref OpenNIRecordAndPlayback "Recording and playing back sensor data").
/// @return true on success, false on failure.
/// @note if the context was already initialized this will fail but the context would be valid!
/// @note This implementation assumes that a depth generator is required for ALL uses including
/// the creation of the skeleton. In theory, it is possible that some implementations will not
/// require a depth generator. This is currently not supported.
