-// This class encapsulates common behavior of a single "block" of data that is
-// stored on a block-file. It implements the FileBlock interface, so it can be
-// serialized directly to the backing file.
-// This object provides a memory buffer for the related data, and it can be used
-// to actually share that memory with another instance of the class.
-//
-// The following example shows how to share storage with another object:
-//    StorageBlock<TypeA> a(file, address);
-//    StorageBlock<TypeB> b(file, address);
-//    a.Load();
-//    DoSomething(a.Data());
-//    b.SetData(a.Data());
-//    ModifySomething(b.Data());
-//    // Data modified on the previous call will be saved by b's destructor.
-//    b.set_modified();
