Configurable Clear-break semantics for range queries

[teh-cmc]

Today, range queries go through their data range without any second thought: if some piece of data was Cleared in the middle of the range, it simply yields an empty array at this specific timestamp, which the system doing the query is free to handle as it pleases.
Only the plot view actually does something with that empty array today: it breaks the curve in half at this timestamp.

It would be nice if range queries could be configured to behave in different ways in the face of Clear events, directly at the query layer, rather than on a per-system/per-view basis.

Consider this dataset:

t=0 [##]
t=1 [####]
t=2 <clear>
t=3 [###]
t=4 [#]

One possibility is to just yield an empty array, like we do today:

Range(0, 4) = [(t=0 [##]), (t=1 [####]), (t=2 []), (t=3 [###]), (t=4 [#])]

Another possibility would be to break the range at the latest sight of a Clear event:

Range(0, 4) = [(t=3 [###]), (t=4 [#])]

In that way the range query effectively behaves as a kind of temporal accumulator, that can be reset by the user at any time.
