* @brief Function declaration keeping track of a "prototype" context
*
* The prototype of a function can be used, in Javascript, to add methods and
* members to the objects instantiated by calling the function.
*
* The prototype is also used to resolve "this". If a function is assigned to
* an object member, its "prototype" becomes the internal context of the object.
* This way, functions assigned to members of the prototype of a class can use
* "this" to refer to the object on which they are called.
*
* @code
* function Class() { this.name = "Me"; }
*
* Class.prototype.print = function() { console.log(this.name) }
* @endcode
