A query should support multiple ranges per dimension. #543

Description

@rwgdrummer

For example,
multiple time ranges
or multiple ranges as defined by multiple polygons.
The code should condense overlapping ranges.
The code should combine the ranges.
For example, given time ranges tr1 and tr2, and ranges sets for latitude and longitude rs1 and rs2,
the following ranges will be decomposed: tr1 with rs1, tr1 with rs2, tr2 with rs1 and tr2 with rs2.
A range set is set of ranges across more the one dimension that are not broken apart for combination. For example, envelopes are represented with ranges over latitude and longitude. Consider two different envelopes; the latitude and longitude ranges should not be intermixed between the two different envelopes. The presentation can be range sets where, in the example, time ranges are a set of one. This concept supports the general case.
