### Class

This is NOT the class definition of ECMAScript 2015 (see [class ECMAScript 2015](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes) for reference).

Class is a special function to help you to declare a class in an easier and compatible way. It works cross-browser, and I hope ECMA could adopt something like that in the future. To let javascript not to be confuse about this, [QCObjects](https://qcobjects.dev) uses "Class" not "class" (note the Camel Case).

#### Usage:

```javascript
Class('MyClassName',MyClassDefinition);
```
Where **MyClassDefinition** is an object with a QCObjects  **prototype**

#### Example:
```javascript
Class('MyClassName',InheritClass,{
  propertyName1:0, // just to declare purpose
  propertyName2:'',
  classMethod1: function (){
    // some code here
    // note you can use "this" object
    return this.propertyName1;
  },
  classMethod2: function () {
    // some code here
    return this.propertyName2;
  }
});

var newObject = New(MyClassName,{
    propertyName1:1, // this initializes the value in 1
    propertyName2:"some value"
});
console.log(newObject.classMethod1()); // this will show number 1
console.log(newObject.classMethod2()); // this will show "some value"

```
