Simple type checks
This is a minimal helper library for type checking in JavaScript. In most
cases you will NOT need it. The only case where this comes handy when
you have to do a lot of type checking in your code. In these cases writing
multiple typeof myvalue === 'whatever'
can become quite noisy.
