Permissionless deployment of Curve metapools.

Wen?

Overview

The metapool factory has several core components:

• Factory is the main contract used to deploy new metapools. It also acts a registry for finding the deployed pools and querying information about them.
• New pools are deployed via blueprints. The implementation contract targetted by the proxy is determined according to the base pool.

See the documentation for more detailed information.
