/*------------------------------------------------- main -----
| Function main
|
| Purpose: Reads input from STDIN using getchar(), iterates over
| each character and determines whether the character
| denotes the end of a sentence or word. After reaching
| EOF, prints output of flesch kincaid algorithm results
| and exits.
|
|
| Parameters: argc (IN) -- number of arguments
| argv (IN) -- Expects the program name, image file, and triples
|
|
| Returns: Only success
