A class used for manual inspection and processing of all picks for the user.
Examples:
region.chooseRectangles():
- lets the user choose several rectangular regions in the plot
region.plotTracesInRegions():
- creates plots (shot.plot_traces) for all traces in the active regions (i.e. chosen by e.g. chooseRectangles)
region.setActiveRegionsForDeletion():
- highlights all shots in a the active regions for deletion
region.deleteMarkedPicks():
- deletes the picks (pick flag set to 0) for all shots set for deletion
region.deselectSelection(number):
- deselects the region of number = number
