Might want specify adding ngHandsontable as a app/module dependency

[jongunter]

I was struggling getting my ngHandsontable to work, then added ngHandsontable to my application module's dependencies and everything started functioning great.

I looked in the docs and this step doesn't seem to be anywhere. Might want to add it.Seems kind of obvious if you're a seasoned Angular dev, but some people will forget. Thanks!
