\tGenerate whole spectrum of possible cases of p4$sw0rDs:

\tExamples:
\t   1. -i Pass strings via stdin:
   
\t      # echo 'foo' | iter-case -i

\t   2. -p Pass string via argument:

\t      # iter-case -p foo

\t   3. -f Pass in file argument:

\t      # iter-case -f dict.txt

\t      switch between 'e' -> '3' etc..
