Added support to clear the AMSampleCamera shapes when a new sample plate is loaded. Seems to be working well. Had to make a new public function to removeSample. Also added access to the AMCameraBrowser from AMCameraBrowserView.
Merge branch 'Issue496' of github.com-acquaman:acquaman/acquaman into Issue496
Added rudimentary database storing to AMSamplePlate and AMSample related classes. Need to work on AMSamplePlateBrowser to get reloading from the database, selection, identification, and whatnot.
