moved to #170
hi, not for merge: just for learning, discussion, and idea sharing

see README and plan.png for the purpose of the contract

---

round 1

• implement root namespace setting
• write how to use this thing more clearly
• use .md over .txt
• inline implementation comments
• split entrypoints to their own files
• removing changes that shouldn't be merged (e.g. removing other native contracts)

prettifying the pull request

[freeranged3v]

still have to format code, documentation etc
but the png and README should help to understand the name registry / namespace concept of the contract.
