Angular Scheduler - Adaptability

When the adaptivityEnabled property is set to true, Scheduler elements adapt to small screens as follows:

Cell overflow indicators become larger to accommodate touch gestures.
The appointment list for a chosen date slides in from the edge of the screen.
The appointment details form occupies the entire screen.
Instead of the view switcher, a drop-down menu is used to switch between views. To open this menu, users should click or tap a button in the upper right corner.

In this demo, we also added the floating action button as an alternative way to create a new appointment. The button is implemented with the SpeedDialAction component.
