Utilities to get and check variable types (isString, isPlainObject, isRegExp, etc)

Why?

Why should I use this instead of say instanceof?

Under certain circumstances instanceof may not return the correct results. This occurs with node's vm module especially, and circumstances where an object's prototype has been dereferenced from the original. As such, for basic == and === checks (like a === null), you're fine not using this, but for checks when you would have done instanceof (like err instanceof Error), you should try to use this instead. Plus things like isPlainObject are darn useful!
