Refinement of swiping back feature

[LN]

@panthonyl

While the enumerator is trained to swipe left to advance the survey the respondent sometimes becomes confused at the direction of "travel"

For that specific need I would recommend changing the navigation style in Collect settings to display forward and back buttons (http://docs.opendatakit.org/collect-settings/#user-interface-settings). This is generally easier for untrained users to understand.

Controlling swiping starting at a specific question was the initial intent of Preventing users from swiping back to earlier questions - #17 by panthonyl. It will require a specification proposal for the XForms spec and for XLSForm.
