This pseudo-class for JavaScript lets you create, extend and inherit 
objects as classes. This allows you to build new objects from other 
instances, that can mutate and change their state or behaviour at 
runtime.


Example:

 function Person( name, age, gender ) {
     this.Construct = function() {
         alert( 'New person created!' );
     };
     this.name   = name || 'unknown';
     this.age    = age || 0;
     this.gender = gender || 'male';
     this.getAge = function() {
         alert( this.name + ' is ' + this.age + ' years old!' );
     };
     this.setAge = function( age ) {
         this.age = age;
     };
 }

 function James() {
     this.job = 'programmer';
 }

 function Snow() {
     this.Construct = function() {
         this.gender = 'female';
     };
     this.job = 'beautition';
 }

 function Mark( name ) {
     this.name  = name;
     this.child = true;
 }

 function Philip() {
     this.Construct = function() {
         this.Inherit( Person, 'Philip', 47 );
         this.age++;
         this.getAge();
     };
     this.inverse = true;
 }

 // extends Person with James

 var james = new Class( Person, 'James', 25 ).Extend( James );

 // same as above, but longer

 var snow = new Class().Extend( Person, 'Snow', 35 ).Extend( Snow );

 // executes the Construct of Parent, which is Person

 snow.Super();

 // inherits current state from an instance of Snow

 var mark1 = snow.Extend( Mark, 'Mark' );

 // overwrite mark's values with snow's

 var mark2 = new Class( Mark, 'Mark' ).Inherit( snow );

 // mark3 extends from snow's default state

 var mark3 = new Class( Person, 'Snow', 35 ).Extend( Snow ).Extend( Mark, 'Mark' );

 // inverse instantiation (see Philip.Construct)

 var philip = new Class( Philip );
