Improved JavaScript type testing - Future revisions will be at https://github.com/wizard04wsu/javascript-type-testing
/**
* A more robust 'typeof'.
* https://gist.github.com/wizard04wsu/8055356
*
*
* For each of the type testing methods, the only parameter is the item to be tested. These methods do not perform coercion.
*
* is(o) - Returns the item's type.
* - NaN is considered its own type (instead of a number), since it essentially represents something that cannot be converted to a number.
* - For objects, the type of the object is given instead of just 'object' (e.g., 'Array').
