-You need to lex and parse WHILE programs, and then generate
-Java Byte Code instructions for the Jasmin assmebler. As
-solution you need to submit the assembler instructions for the
-Fibonacci and Factorial programs. Both should be so modified
-that a user can input on the console which Fibonacci number 
-and which Factorial should calculated. The Fibonacci program
-is  given in Figure~\ref{fibs}. You can write your own program
-for calculating factorials.
