Project structure skeleton
CuckooSet interface

This interface will implements a set using cuckoo hashing.
At the moment, it contains a quick and dirty dummy implementation based
on std::set and std::mutex.

It compiles and is ready to plug into pheet benchmarks.
Update README for task 2
Unit testing infrastructure
Remove unused functions from set interface
Additional sequential test cases
A couple of parallel smoke tests
Lower test iteration counts

Else we run into test timeouts.
Copy the std::set-based set to StdSet

It might be handy for benchmarks or tests later on.
Hash function prototypes
An empty ProbeSet wrapper
Implement ProbeSet using std::set
Strip the current temporary CuckooSet implementation
Initialize and free the internal ProbeSet table
Initialize the_size to 0
Add a custom LockGuard implementation
Add contains_nolock()
Add an early release to LockGuard
Initial work on put()
The remove() function
