## Basic example showcasing a migration using the MBM framework This PR has been built on top of https://github.com/paritytech/polkadot-sdk/pull/1781 and adds two new example crates to the `examples` pallet ### Changes Made: Added the `pallet-example-mbm` crate: This crate provides a minimal example of a pallet that uses MBM. It showcases a storage migration where values are migrated from a `u32` to a `u64`. --------- Signed-off-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> Co-authored-by: Liam Aharon <liam.aharon@hotmail.com>
