Data type checker

function

'Is' is a very small module that smoothes over some of the gotchas in JavaScript type checking. It behaves the way you (or rather, I) would expect type checking to work -- e.g., is.object() only works on objects that are neither arrays nor regular expressions. It also makes indexOf() easier to use, and provides search functions. Works in Node; should work in browser as well, exporting a variable 'is' into the global namespace.

Chainable validation based on `validator`, `lodash`, `moment` and `type-detect` with syntax almost looks like chai.js combine with sync or async report and non 'throw' ing things around so that you don't have to 'try' and 'catch'.
