+ Multiple Constructors
+
+ A class can have multiple constructors that assign the fields in different ways.
+ Sometimes it's beneficial to specify every aspect of an object's data by assigning
+ parameters to the fields, but other times it might be appropriate to define only
+ one or a few.
+
+ Advanced example written in Python Mode by: Prabhjot Singh (NITH)
