Plain Sort for ordered types

[clipperhouse]

Currently (on the projection branch), we have a standard method for SortBy, which takes a func to define less.

Many types can simply be evaluated as greater or less (‘ordered’ in Go’s terminology). Create a Sort method, which does not require a passed func, for types that pass the test of being ordered.

This will not require the big re-implemented Sort template; rather just satisfy the sort package’s Interface for these types, and wrap in a simple method that returns a sorted copy (instead of sorting in place).
