- Creation of transaction observer service that takes `TxObserver`s and registers them against keys and for sets of attributes.
- Observer service called when InProgress commits and filters observers that are affected by the tx's that occured and notifies them of what changed
- InProgress batches up tx's as it goes along so granular notification can be provided.
You can use this in conjunction with setting SQLITE3_LIB_DIR to control which SQLite is used.

This was done using the following shell script:
```
find . -type f -not -path "*target*" \
'(' -name '*.rs' -o -name '*.md' -o -name '*.toml' ')' -print0 | \
xargs -0 sed -i '' -E 's/[[:space:]]*$//'
```
Which is admittedly imperfect, but manages to hit everything that was a problem in this repo.
