[boost] [epochs] Proposal for an epoch-based organization of Boost libraries

Hi, Prompted by general feelings about Boost perceived lack of modernization and internal "bloat", and after an explicit survey on what users dislike about Boost [1], I decided to try and write a more or less fleshed out proposal for an epoch-based organization of Boost libraries. I've extensively tested and refined the proposal during discussions on Reddit and the Boost Slack channel, and I feel this is now ready for presentation at the mailing list: https://github.com/joaquintides/boost_epoch/blob/master/README.md I hope the proposal can start a productive conversation. Looking forward to your feedback. Best, Joaquín M López Muñoz [1]: https://www.reddit.com/r/cpp/comments/gfowpq/why_you_dont_use_boost/
