 * Move type aliases and core types to near-sdk to avoid coupling. [PR 415](https://github.com/near/near-sdk-rs/pull/415).
 * Implements new `Lazy` type under the new `unstable` feature which is a lazily loaded storage value. [PR 409](https://github.com/near/near-sdk-rs/pull/409).

 ### Payable methods
-We can allow methods to accept token transfer together with the function call. This is done so that contracts can define a fee in tokens that needs to be payed when they are used. By the default the methods are not payable and they will panic if someone will attempt to transfer tokens to them during the invocation. This is done for safety reason, in case someone accidentally transfers tokens during the function call.
