+/**
+* A class for storing memory entries when the server is informed that memory has been
+* allocated. The class stores the memory address of a new allocation and a pointer to
+* a buffer including the current call stack. It also stores a time stamp, and the size
+* of the allocation.
+* The class has member methods for evaluating two different objects of this class
+* with each other. In the construction the class takes a pointer to the call stack
+* buffer, but it does not create the buffer itself. However, it is responsible for
+* deleting the buffer in the destruction.
