# Objective
- Allow viewing and setting the added tick for change detection aware
data, to allow operations like checking if the value has been modified
since first being added, and spoofing that state (i.e. returning the
value to default in place without a remove/insert dance)
## Solution
- Added corresponding functions matching the existing `changed` API:
- `fn added(&self) -> Tick`
- `fn set_added(&mut self)`
- `fn set_last_added(&mut self, last_added: Tick)`

## Testing
- Running the bevy test suite by.. making a PR, heck.
- No new tests were introduced due to triviality (i.e. I don't know what
to test about this API, and the corresponding API for `changed` is
similarly lacking tests.)
