/**
 * (...values) => (...types) => value||[values]
 *
 * This is a curried function to help with type checking your javascript.
 * It is curried in two parts, the first part taking the values that you
 * wish to type check, the second part of the curry takes the types you wish
 * to validate them with.

// This gist illustrates a very simple strategy of declaring and exposing
// dependencies for your modules. Allowing them to be overridden for 
// tests (or other), and providing a mechanism to restore the original
// dependencies.
// It's a work in progress, is very simple and naive, but its a simple
// mechanism to achieve required results without having to depend on
// any complex DI frameworks.
