* allow Rocca to run without classifiers
Fixed bug that threw an error if no classifier files were specified in Rocca Params dialog
* add rocca switch to enable dev mode
currently only shows/hides extra buttons in the Params dialog, but will
extend to more options in the future
* Fix memory issue with RoccaContourDataBlocks not being released for
garbage collection
Set RoccaContourDataBlock objects to null and stop PamObserver Timer to
force release
* Fix problem tracing whistles in Rocca spectrogram pop-up
Whistle and raw data were being cleared before the user had time to trace out the whistle, causing PAMGuard to throw an exception. Both were already being cleared when the pop-up window is closed, so no need to do it here.
* updated for training/testing classifiers
Made an enum for the different collections. More robust than passing the
names around as strings. Contains functions for converting between the
collection name and the documents names within those collections.
* Bugfix for OverlayMarks
Check for a null pointer exception in OverlayMarks that was causing a crash on startup.
* Bugfix for null pointer in symbol manager
Fix a bug that I found where the DIFAR module was crashing the symbol manager. Seems that this was due to this subclass of clip generator having a null value for it's uniqueName. I've fixed by checking for null values and assigning a generic symbol when null.
* DeepLearning detections canGenerateClips=true
Set flag in DeepLearning detector so that detections are considered 'clips' by Pamguard. This allows them to be processed automatically in the DIFAR Localisation module (and maybe others).
* DIFAR: bugfix frequency limits for auto-detections
Fix a bug in DIFAR module where the frequency limits of automated detections were not being set properly by the DIFAR module.
* DeepLearning - Bugfix to detection duration
Fix bug in deep learning detector where duration (in samples) was being set to number of samples in a hop instead of the number of samples in a segment.
Bug in logger forms annotatoins. Crashing when a data field (i.e.
latlong) had > 1 database field.
Also added data selector to Detection grouper list display and fixed
feature in screen position which had a nasty habit of moving the display
to monitor 0 on multiscreen setups.
