The class to wrap memory for dispatch I/O operations.
Example 
// make a memoryblock
Var m As New MemoryBlock(100)
m.StringValue(0,5) = "Hello"

// wrap into data obect
Var d As New DispatchDataMBS(m)
Var size As Integer = d.Size

// copy back out
Var data As MemoryBlock = d.CopyData
// and check content
Var da As String = data.StringValue(0,5)

// release it
d = Nil

Dispatch data objects describe contiguous or sparse regions of memory that may be managed by the system or by the application.

Dispatch data objects are immutable, any direct access to memory regions represented by dispatch objects must not modify that memory.

We usually just wrap a MemoryBlock and avoid copying it for better performance.
