-Implements Spring Boot and spring dependency injection - significant code refactoring.
-Creates database repository with Calls table
-Implements AudioManager to update database and manage audio recordings.
-Calls paging and searching
-Adds audio recording to wave file and places file in the calls database table.
-Audio spectrum view with 64 bins.
-Updates audio playback manager to process the incoming calls queue and support auto, auto-locked, replay, and mute playback modes.
-Adds channel lock/unlock and mute/unmute features.
-Adds column configuration editor to change column order & visibility and adds table state monitoring to save any user customization of the column ordering.
-Adds call table column sort ordering to the saved table state and restores the sort on application launch.
