## Description
The `cuckoo.MinimumLoad()` option was not a very useful option, and prone to error. By removing the ability to modify it, and setting it to something reasonable (like 5%), we can remove a whole set of errors that the user may stumble into.
## Changes
- Remove `MinimumLoad()` option.
- Privated `DefaultMinimumLoad`.
### Design Decisions
- `DefaultMinimumLoad` should be privated because it is no longer an option. The user should not need to interact with it.
## Checklist
- [x] Tests pass
- [x] Docs updated
