Goals 
	Learn to give detailed instructions.
	Learn to submit files on EASEL.

Task - Write, in English, instructions that can be used to 
determine if a given date is valid.  An individual following
your instructions should start with a year, month and day in 
mind and by a series of simple mathematical operations 
and observations determine if the date is valid.  You can assume
that the person following your instructions will stop when a
conclusion is reached. The algorithm should take leap years 
into account.

Primitives:
•	Addition
•	Subtraction
•	Multiplication
•	Division with remainders
•	Numerical Comparison

Note:  This is intended to be simple.  Do not make it too complicated.
I just want to get you thinking about giving detailed instructions.

Submit your instruction on EASEL as a text file.
