- Full implementation of TDB2::add, which includes pending/completed, undo
and backlog.
- Removed obsolete TF2::commitUndo, which is no longer necessary.
- Added File::truncate method, to allow a TDB2 shortcut.
- Made locking an integral part of the File object, so that a client
may now call File::lock multiple times with no effect beyond the first
call. This simplifies situations like the 'cal' command that must scan
for recurrence changes, modify tasks, then optionally run a second
report, all without locking issues.
- Merged Path, File and Directory handling objects from metatask.git.
- Merged unit tests.
- These objects will replace a fair amount of code in task 1.9 and
more in 2.0.
