Adding a Resource with API

To add a resource to the registry instance, create a Resource object and then pass the created resource object to the registry instance's put method:

Create a collection called "/c1/c2" in the org.wso2.carbon.registry.core.CollectionImpl class.
```
Collection collection = registry.newCollection();
```
Call the put method.
```
registry.put("/c1/c2", collection);
```

If you call the get method, then you will be able to access that created resource. You can also use the set method to set the value of the resource in the org.wso2.carbon.registry.core.Registry class. For example:

//set property
registry.setProperty("propertyName", "value")

//get property
registry.getProperty("propertyName");

To add a resource with content, create a Resource object in the org.wso2.carbon.registry.core.Resource and then set content.

Resource r1 = registry.newResource();
String str = "My File Content";
r1.setContent(str.getBytes());
registry.put("/c1/c2/r1", r1);
