Set the duration of the contract in the Dates Spoke.

Membership, Agreement, Pass Plans all have the Dates spoke listed first in the config list.

• Fixed dates mean all contracts will have the same start and end date.  The plan can still be sold after the start date has passed
• Fixed Duration means the contracts last for the same duration, from the date of purchase/completion.
• Open Ended means this contract has no end date.  Use this for recurring
