// - Convert the string to only have printable characters in it. Control
//      characters are converted to hat notation, spaces are converted to "SPC"
//      (to be able to see them at the end of a string), and DEL is written as
//      "\x7f".
// Arguments:
// - inString: The string to convert
// Return Value:
// - a string with only printable characters in it.
