Base class that calls user-defined functions on down, move and up
events. This class also manages "drag sequences".
When the handleDownEvent user function returns true a drag sequence is
started. During a drag sequence the handleDragEvent user function is
called on move events. The drag sequence ends when the handleUpEvent
user function is called and returns false.

Description
handleDownEvent
function
Function handling "down" events. If the function returns true then a drag
sequence is started.
handleDragEvent
function
Function handling "drag" events. This function is called on "move" events
during a drag sequence.
handleEvent
function
Method called by the map to notify the interaction that a browser event was
dispatched to the map. The function may return false to prevent the
propagation of the event to other interactions in the map's interactions
chain.
handleMoveEvent
function
Function handling "move" events. This function is called on "move" events,
also during a drag sequence (so during a drag sequence both the
handleDragEvent function and this function are called).
handleUpEvent
function
Function handling "up" events. If the function returns false then the
current drag sequence is stopped.
stopDown
function
Should the down event be propagated to other interactions, or should be
stopped?
