> The InodeDiffList class contains a generic List to store snapshotDiffs. The 
> generic List interface is bulky and to store and manage snapshotDiffs, we 
> need only a few specific methods. 
> This Jira proposes to define a new interface called DiffList interface which 
> will be used to store and manage snapshotDiffs.
