phaseExample of a Rappture <phase> object.
A phase is like a group of input controls, but it represents a whole page within the graphical interface. A complicated tool may have too many controls to fit on one page, even if you use groups. Or, it may have a series of tasks that must be linked together to form a complete analysis. Each page of input is represented by a phase.
Note that instead of a Simulate button, the phases are arranged one after another, in a Next, Next, Next manner. The very last Next operation is Simulate.
