This module produces a function that creates and returns a target object which inherits from another object. The syntax used internally is "Object.create()" and this module is meant to provide a cleaner and better looking solution with the added benefit of "sub-classing" arrays, or effectively having an array inherit from any object (including null). The benefit of this is that you do not have to pollute Array.prototype when a custom array method is desired.
Thank you to kangax for the article on subclassing arrays. I used his method of creating an object and giving it the special characteristics of an array manually. The article can be seen here: http://perfectionkills.com/how-ecmascript-5-still-does-not-allow-to-subclass-an-array/
The argument of the function must be an object. The accepted optional properties are:
[ proto ] : the desired prototype of the newly created target object. if [ target ] is an array, [ proto ] defaults to Array.prototype, otherwise it defaults to Object.prototype
[ target ] : The new object to be created. This may be an array. Literal syntax is recommended since a shallow copy of the properties will take place.
[ descriptors ] : The descriptors of the object may be defined here.
If both [ target ] and [ descriptors ] are not defined, the function will return an empty object.
