transfer

An entrypoint that transfer user's LP tokens to another account (tz/KT). Also it votes for sender's and recipient's bakers. If the recipient does not have a preferred baker, the current delegated will be chosen as the preferred baker. Works exactly like FA2 transfer entrypoint according to TZIP-012. Also supports TZIP-017 (permits).
