public String toByteString() {
		return Bits.toByteString(toByteArray());
	}
Convert a binary representation of {@code this} bit-array to a string. The
string has the following format:
<pre>
 Byte:       3        2        1        0
             |        |        |        |
 Array: "11110011|10011101|01000000|00101010"
         |                 |        |      |
 Bit:    23                15       7      0
</pre>

@return the binary representation of {@code this} bit array.
