'''
Write a program that calculates the populations of two kinds
of "wumpuses" over time. At the beginning of year 1, there are
1000 slow wumpuses and 1 fast wumpus. This one fast wumpus is
a new mutation. Not surprisingly, being fast gives it an advantage,
as it can better escape from predators. Each year, each wumpus has
one offspring. (We'll ignore the more realistic niceties of sexual
reproduction, like distinguishing males and females.). There are
no further mutations, so slow wumpuses beget slow wumpuses, and
fast wumpuses beget fast wumpuses. Also, each year 40% of all
slow wumpuses die each year, while only 30% of the fast wumpuses
do.

So, at the beginning of year one there are 1000 slow wumpuses.
Another 1000 slow wumpuses are born. But, 40% of these 2000
slow wumpuses die, leaving a total of 1200 at the end of year
one. Meanwhile, in the same year, we begin with 1 fast wumpus,
1 more is born, and 30% of these die, leaving 1.4. (We'll
also allow fractional populations, for simplicity.)

Beginning of Year	Slow Wumpuses	Fast Wumpuses
1					1000			1
2					1200			1.4
3					1440			1.96
