 Description   

In particular, we need to ensure that spread and area calculations make sense for all histogrammable types.

Currently dates, objectids, strings, and timestamps are converted to doubles so histograms can be computed, but there is no guarantee that the mapping is accurate.

This will be done as part of SERVER-71205 which fixed the mapping to double for a few types. The other type mappings are already at least partially tested in CE unit tests.
