usage: $new_password = return_password();
Sample: generated passwords: 2X5bjj2z, ERgid62Y, p2sHtDPv

function return_password () {

// set password length
$pw_length = 8;
// set ASCII range for random character generation
$low_ascii_bound = 50; // "2"

// Exclude special characters and some confusing alphanumerics
// o,O,0,I,1,l etc
