DI COSTANZO updated MATH-682:
-----------------------------

    Attachment: PascalTriangle.java
                PascalTriangleTest.java

I agree with you. It could be important to prevent too large entries. 
In the files newly added, I add a static variable defining the maximum order at 
which a row can be computed (arbitrary set at 50). If the entry is superior to 
this maximum value, another method is called and only compute the individual 
row. The user can arbitrary call any one of the method.
I updated the previous test class.
