Added mmspoint class, which contains 2 persons username and their point.
Added function in pointmanager to get a point object upon the input of
teo persons. Added personmanager class and function in it which will
retrieve a person object on a username input. This can be used in
profile view also. Added a pointcalculator jsp and servlet for the
testing. It works fine but some values of person object is not set in
the database correctly.
Corrected the error(in setDiet).
