@seamuslee001 -per brief discussion - here is the comment docblock

  /**
   * Is there a processor on this site with the specified capability.
   *
   * The capabilities are defined on CRM_Core_Payment and can be extended by
   * processors.
   *
   * examples are
   *  - supportsBackOffice
   *  - supportsLiveMode
   *  - supportsFutureRecurDate
   *  - supportsCancelRecurring
   *  - supportsRecurContributionsForPledges
   *
   * They are passed as array('BackOffice');

But the issue is that many pages check for 'are there live processors' more than once so the goal here is to add caching once the question is answered

I guess the capabilities make for an OK array key i guess

lol - that's for the enthusiastic review.. I guess

I am happy with the code and and think it won't do any harm and will hopefully improve performance

much more enthused - I'm going to merge it off that since I think the test coverage is solid on this
