Variable Pricing License Expiration

/**

  * Below are two different filters: one to modify the unit (months, years, or days), and another

  * to modify the length. They are used together to build a full billing cycle for that price ID.

  * So if you enter "months" for price ID 1 in the first filter, and "6" for price ID 1 in the second

  * filter, you get a duration of "6 months".
