Diffa Diffa → 1.0

When you specify a null upper bound (and I presume the same is relevant for lower bounds), e.g.

<range-category name="bizDate" data-type="date" lower="2009-10-01" max-granularity="individual"/>

the agent fails to apply the configuration with this error:

15:00:01.751 [akka:event-driven:dispatcher:global-9] ERROR PairActor:362 - Failed to difference pair diffa/Staging7
