/**
Returns a flattened list of rate periods where “flattened” means that any
overlaps have been resolved by favoring the greatest nightlyRate for the
duration of the overlap.
Example:
flatten [(2015-01-01, 2015-12-31, 125), (2015-03-07, 2015-03-21, 175)]
Output:
[(2015-01-01, 2015-03-06, 125),
(2015-03-07, 2015-03-21, 175),
(2015-03-22, 2015-12-31, 125)]
Viz:
Jan 1 |------------------------------125------------------------------| Dec
31
Mar 07 |----175----| Mar 21
Output:
Jan 1 |-----125-----|----175----|----------------125------------------| Dec
