v2.0.0-beta.14

Minor Changes

• #65 8f69bef Thanks @Psvensso! - meta.filter.operators narrows the operators a column offers to a subset of
  its type's, for columns backed by an endpoint that answers only some of them.
  The panel dropdown and the header funnel show only those; a fresh filter opens
  on the type's default when it is offered, else on the first offered operator.
  New export getColumnOperators(column).
