Detailed Description

This is were the magic happens. All types in Om inherit from the DataClass. This class includes an allocation_count, which remembers how many time the object is supposed to be on the heap. This is similar to a reference counter. However, the first bump from zero allocation count to 1 is performed by making an explicit shallow copy towards the heap and returning that as value.
