Function            getci_match - get specific input, case
                                      independent

  Syntax              char getci_match(boolean output, char *match);

  Prototype in        keyboard.h

  Remarks             getci_match accepts character input (via getk())
                      until one of the characters in the string match in
                      entered, case independent ('a' == 'A'). Extended
                      keys never match (F10 will never be a match.) If
                      output = TRUE, the character is echoed to the
                      screen via putch().

  Return value        returns the key pressed.
