 ## `CodeSnippet` Class
 Each `CodeSnippet` represents the lines of code between two consecutive author tags that were written by an 
 `Author`. Since this code belongs to a file, a `SourceFile` object is associated with each `CodeSnippet` object.

+in a table easily without sacrificing the semantics of the `Author` class.
