DejalIntervalPicker is a custom Mac control similar to NSDatePicker, but for time intervals or ranges.

Features:

• A custom control with an amount or amount range, units, and stepper.
• Like NSDatePicker, editing components separately, with a stepper.
• Can set minimum and maximum amounts.
• Can get/set the interval as a DejalInterval, as individual values, or as a NSTimeInterval.
• Can have either a single amount or a range of amounts.
• Can optionally filter the range to ensure the first amount is smaller (or equal to) the second one, or vice versa.
• Can control which units to include.
• Can navigate between components via Tab and Shift-Tab and left/right arrow keys, or clicking.
• Can type amounts just like in the date picker, and units with auto-completion.
• Can increment and decrement amounts and units via up/down arrow keys, +/- keys, or the stepper.
• Can increment/decrement in steps of 5 via Shift/Option/Ctrl and up/down arrow keys, or Page Up/Down.
• Can go to the first/last valid values via Home/End.
• Can display a drop-down menu of suggested legal amounts or units via the spacebar or clicking on the selected value.
• Supports regular, small and mini sizes.
• Supports properties, key-value coding, and bindings.
• Supports IB_DESIGNABLE and IBInspectable, so the picker can be configured in IB.
• A demo project is included.

• If set, a -view:hitTest:withEvent:hitView: method is invoked on the delegate.
• That delegate method can return the passed view to act normally, or return nil to ignore the tap.
