public default AddressableByteSource getByteSource() {
		return new ProgramByteSource(getProgram());
	}
Returns a source for providing byte values of the program associated with this navigatable.
<p>
For a static program, this is just a wrapper for a program's memory. But dynamic programs
require special handling for reading bytes.

@return a source of bytes for the navigatable's program
