Bernstein-Vazirani Algorithm

In our last meetup we went through phase kickback and spent a lot of time working through circuit calculations. Our next meetup will have a similar format as we tackle the Bernstein-Vazirani algorithm. Once again we'll use the Qiskit textbook as our guide. Feel free to read before we meet: https://qiskit.org/textbook/ch-algorithms/bernstein-vazirani.html
