This centralizes updates to recurrence and 'until' in Command, instead
of doing so in each individual command implementation.
This is preparatory to opening the TaskChampion replica in read-only
mode.
It's possible to call getDOM without a contextual task. Previously,
this was done by referencing a "dummy" task which necessitated a way to
distinguish such dummy tasks. This switches to using a pointer and
treating the NULL value as meaning there is no context.
Note that this cannot use `std::optional<&Task>`, as optional does not
support reference types.
- It is an error to provide no DOM references (task _get).
- It is an error to provide bad DOM references (task _get donkey). In this
example, 'donkey' could be a UDA orphan.
- It is not an error for a valid DOM reference to yield no value.
- Standardized DOM interface to return success/failure, with the possibility
of blank values. This matches the Eval::source callback interface‥
- Added more unit tests.
