Added tests for using a lookahead for the zkd index (see PR #14745 in arangodb). There is a new tests set:
documentZKDTestsand two new test functions:zkdIndexfor queries with filters(p.x > xMin) AND (p.x < xMax)and(p.y > yMin) AND (p.y < yMax)zkdIndexExactValuefor queries with filters(p.x == x) AND (p.y == y)where we find values forxandybeforehand just after filling the database with values such that there is a match in the database.The following values for lookaheads are tested: 0, 2, 4, 8, 16, 32. To obtain a more visible difference between the query times,
hugecollections are added that contain 20 millions of documents. For consistency, thehugeoption is added also for other tests.
