/// The so-called parameter type can be created in three different ways:
///
/// - Using `const` to create a parameter type that provides a `const` getter.
/// It is required that the `value` is const.
///
/// - Declare the parameter type without `const` to have more freedom when creating the value.
///
/// - Using `storage` to create a storage parameter type. This type is special as it tries to
/// load the value from the storage under a fixed key. If the value could not be found in the
/// storage, the given default value will be returned. It is required that the value implements
/// [`Encode`](codec::Encode) and [`Decode`](codec::Decode). The key for looking up the value

///
/// `twox_128(":" ++ NAME ++ ":")` where `NAME` is the name that is passed as type name.
