Created the beginning of SelectionBoxView, a custom view component which extends ImageView in order to override the default ImageView's measuring code in order to correctly size the selection box.
Added a new tag class which stores an enum representing the type of drag operation to differentiate between actually dragging the selection box and resizing it.
Added code to handle resizing, four new cases in the onDrag event handler for handling resizing using each of the four corners of the selection box as handles.
Fixed a small issue with the resizing code
Added SoundRecordActivity which will eventually handle sound recording as well as an xml layout for it. Added a new button to allow the user to get to the audio recorder interface, registered an onClick method for it which is currently empty. The Open Picture button now moves to the left after opening a picture to prevent overlap with the Record Audio button
