Input:
- a <directory>
- a list of <protected-files>
- a list of <stored-files>

Code a script that fetches the list of files in <directory> and:
1. if it's listed in <protected-files>, ignore it
2. if it's not listed in <stored-files>, add it
3. if it's listed in <stored-files>, delete it from <directory> and from <stored-files>

Features:
- must keep files up to date
- must handle names with spaces and special characters
- must reliably run multiple times (e.g. cron)
- must handle inconsistencies (e.g. file listed in <stored-files> but not in <directory>, file listed in both <protected-files> and <stored-files>, malformed input)
