The official app and website for documentation of QCObjects

### Package
Defines a QCObjects package and returns it.

#### Usage:
```javascript
Package('packageName',[packageContent]);
```
Where packageContent is an array of QCObjects Classes. If you only pass the packageName param you will get the previously declared package content.

#### Example (1):
```javascript
'use strict';
Package('org.quickcorp.main',[
  Class('Main',InheritClass,{
    propertyName1:'propertyValue1',
  }),
  Class('MyCustomClass',InheritClass,{
    propertyName2:'propertyValue2',
  }),
]);
```
#### Example (2):
```javascript
let mainPackage = Package('org.quickcorp.main'); // this will return the previously declared content of package 'org.quickcorp.main'
// mainPackage[0] will be the Main class definition.
// This is useful for code introspection
```

The packages loading technique present in QCObjects is promise based and also scope oriented. You can ask if a package is loaded simply calling the Package() function passing a package name as an argument.
