SYNOPSIS
string invert_bits (string str)

DESCRIPTION
Invert the status of all bits in bitstring <str> and return the
new string.

Note that the total number of bits (ie the string length) stays
the same.

EXAMPLES
string s;

s = set_bit("", 3); s = set_bit(s, 4); s = set_bit(s, 15);
--> s is now "8 ("

invert_bits(s) --> returns "G_W"
