Multi-dimensional Data Access minimal requirements

[Patrick Dowler]

The summary of requirements I quoted says they want to be able to 
constrain the field of view (size), which I interpret as, for example:

  "find data with field of view larger than 1 degree across"

or something like that. So this is unrelated to POS and just a simple 
constraint on a single numeric column in ObsCore.

OK, +1 for EXPTIME
