+HOW TO IMPLEMENT TESTS FOR OTHER DATA STRUCTURES
+
+Data structures that support the following functions: 
+- check if structure is empty
+- check if structure contains a specific element
+- insert an element in the structure
+- erase an element from the structure
+should be easily checkable using the Set specification contained in the 
+src/sequential_datastructures.h file.
+In general, the checker needs a sequential implementation test against the
+concurrent one (the EMBB one). The implementation should support efficient equality checks
+and efficient memory management. Stick to the implementation of the already integrated
+structures (stacks, queues..) for future integration. 
+After adding the implementation of the datastructure, it is necessary to add a worker and
+experiment for the newly created datastructure in main.cc. Stick again to the already
+implemented functions (it should be sufficient to change the name of the methods that are called
+on the EMBB structure).
