SYNOPSIS
int last_bit (string str)

DESCRIPTION
Return the number of the last set bit in bitstring <str>.

Each character contains 6 bits. So you can store a value
between 0 and 63 in one character (2^6=64). Starting character
is the blank " " which has the value 0. The first character in
the string is the one with the lowest bits (0-5).

EXAMPLES
string s;

s = set_bit("", 4); s = set_bit(s, 2);

last_bit(s) --> returns 4
