An extension to the BuildReport class that tracks how Assets contribute to the size of the build.
The build process generates a PackedAssets report for each .sharedAssets or .resource file, or for each AssetBundle.
| contents | An array of PackedAssetInfo objects that holds information about the Assets that are included in the PackedAssets bundle, such as packed Asset size and type. | 
| overhead | The header size of the packed Asset file. | 
| shortPath | The file path to the Asset package, relative to the Data folder of the build. | 
| hideFlags | Should the object be hidden, saved with the Scene or modifiable by the user? | 
| name | The name of the object. | 
| GetInstanceID | Gets the instance ID of the object. | 
| ToString | Returns the name of the object. | 
| Destroy | Removes a GameObject, component or asset. | 
| DestroyImmediate | Destroys the object obj immediately. You are strongly recommended to use Destroy instead. | 
| DontDestroyOnLoad | Do not destroy the target Object when loading a new Scene. | 
| FindAnyObjectByType | Retrieves any active loaded object of Type type. | 
| FindFirstObjectByType | Retrieves the first active loaded object of Type type. | 
| FindObjectsByType | Retrieves a list of all loaded objects of Type type. | 
| Instantiate | Clones the object original and returns the clone. | 
| InstantiateAsync | Captures a snapshot of the original object (that must be related to some GameObject) and returns the AsyncInstantiateOperation. | 
| bool | Does the object exist? | 
| operator != | Compares if two objects refer to a different object. | 
| operator == | Compares two object references to see if they refer to the same object. |
