  Basic functions keyboard functions:
    kbhit ()      checks if keyboard was pressed.  It installs also our
		  keyboard handling hook function for the QUICK WIN apps.
    fkey_kbhit () returns SD_FALSE most of the times. Only every KBHIT_PERIOD
    		  (50-th time when called) it will return the return
    		  from the call to the kbhit () function.
    		  This function may be absolete.
    getch ()      returns the ASCII value of a pressed key.  The kbhit ()
    		  function should be called first to see if the keyboard
    		  was pressed.  The function will install our keyboard
    		  handling hook function for the QUICK WIN applications,
    		  if not already installed.
    flush_keys () flushes the keyboard character buffer.
    get_a_char () will wait for the keyboard hit and return the ascii
		  code for the character.  In addition the function will
		  echo the character to screen.

  Functions to display a message and wait for user to hit a key:
    wait_debug_log () outputs the str to a fptr (which may be stdout).
    		  If the output is stdout the function will wait for user
    		  to hit a key.  During waiting the function will call
    		  the servefun () to execute background processing.
    wait_msg ()   outputs the str to stdout.  The function will wait for
    		  user to hit a key.  During waiting the function will call
    		  the servefun () to execute background processing.
    wait_key ()   waits for user to hit a key.  During waiting the function
    		  will call the servefun () to execute background processing.
    err_msg ()    outputs the str to stdout.  The function will wait for
    		  user to hit a key.  Note that this func will NOT call
    		  the servefun () while waiting for the keyboard input.
    ask ()        asks a yes/no question and return the answer.
    		  SD_TRUE will be returned if the answer is 'y' or 'Y';
		  SD_FALSE will be returned if the answer is 'n' or 'N';
		  if user presses the ENTER key the default answer will
		  be returned.
    key_err ()    displays a message and returns shortly after, used to
    		  display error	messages without waiting for user to hit
    		  a key to continue.
