MLDB-2194 double timestamp column format #891

Closed jeremybarnes closed 7 years ago

jeremybarnes commented 7 years ago

Reduces memory usage for doubles from 12 to 8 bytes/entry, and from timestamps from 12 to 8 or much less if they are integers.

It also puts in place a mechanism that frozen columns can use other frozen columns as part of their implementation.

Test failure is again the same spurious on on master.
