RPStep class
The base class for steps which can compose a task.
Each RPStep object represents one logical piece of data entry or activity in a larger task. Whether your app is giving instructions, presenting a form or survey, obtaining consent, or running an active task, everything in the Research Package framework is a collection of steps (RPStep objects), which together form a task (an RPTask object)
