In EiffelWorld, EiffelBuilders build
Eiffel Towers. We can specify the initial size of the Eiffel
Towers (ie the length of one side), the shrink factor for each
successive level, the angle of the structure, the number of
levels to build, and how far apart (the offset) the
levels of the Eiffel tower should be. When we create an
EiffelBuilder ellie, she starts at a specific
place with her pen down and facing the top. If we ask her to build an
Eiffel tower with fewer than one level, she does nothing. She builds
a one level Eiffel tower with the tip at her starting position.
Regardless of the number of levels in the Eiffel tower she builds,
ellie stands in her initial position facing her initial
direction when she is finished. The following pictures illustrate the
result from asking ellie to build Eiffel towers with different
numbers of levels.

Our task is to fill in the code for the eiffelTower
method in the EiffelBuilder class. The following
skeleton is provided for us.
public void eiffelTower (double size, double shrinkFactor,
double angle, int levels, double offset) {
System.out.println("eiffelTower("+size+", "+shrinkFactor+
", "+angle+", "+levels+", "+offset+");");
// add your code here
}
We may also want to define auxiliary methods in the
EiffelBuilder class. We should not need to modify the
EiffelWorld class in order for our code to work.
However, we may modify it during testing.
