SYNOPSIS
function visible(input) result(output) 

    character(len=*),intent(in)           :: input
    character(len=:),allocatable          :: output

DESCRIPTION
visible(3f) expands characters to commonly used sequences used to represent the characters as control sequences or meta-control sequences.

EXAMPLES
Sample Program: 

    program demo_visible
    use M_strings, only : visible
    integer :: i
       do i=0,255
          write(*,’(i0,1x,a)’)i,visible(char(i))
       enddo
    end program demo_visible

BUGS
The expansion is not reversible, as input sequences such as "M-" or "^a" will look like expanded sequences.
