Merge branch 'master' of https://github.com/anudeepreddy/algorithm-visualizer into anudeepreddy-master

Closes #264

getWrappedInstance() is no longer necessary.

If {forwardRef : true} has been passed to connect, adding a ref to the connected wrapper component will actually return the instance of the wrapped component.
