* including the following types:
* <ol>
* <li>Slide - the exiting form slides out of the screen while the new form slides in (can be vertical or horizontal). </li>
* <li>Slide Fade - slides the content pane while fading the title. This is the default iOS transition. </li>
* <li>Cover/Uncover - like slide only one of the forms remains in place while the other moves. </li>
* <li>Fade - components fade into/out of the screen<li>
* <li>Timeline - uses an animation image as an alpha mask between the source/destination</li>
* </ol>
