/**
* This class represents a slide to unlock control. This control's metaphor is to prevent a user from
* accidental input via keyboard, touch, or mouse. The user would need to actively slide the button
* to the far right to unlock, thus allowing the user to proceed. When using a mouse the control would
* detect a mouse press, dragged, and release. When using a touch enabled devices the control can detect
* a touch press, touch dragged, and touch release events.
