public int getNumBytes() {
		return numBytes;
	}
Returns the number of bytes spanned by this Register.

<p>
Compare to {@link #getMinimumByteSize()}: Suppose a 5-bit register spans 2 bytes: 1 bit in
the first byte, and the remaining 4 in the following byte. Its value can still be stored in 1
byte, which is what {@link #getMinimumByteSize()} returns; however, its storage still spans 2
bytes of the base register, which is what this method returns.
