Purpose: Implement an action bar in the Split the Bill app to include new features.
Requirements: Using the previous version of the Split the Bill app add an action bar that will have two items.
The first item should allow the user to select if they pay a tip on only the purchased items or on the total which includes taxes. This may require extra fields to allow the user to separate the purchases from the tax included total.
The second item would allow the user to enable or disable payment rounding. This option, when enabled, should round the amount that each individual needs to pay up to the next whole dollar.
