Create VB.net classes for collecting file details

Create vb.net classes for iterating over a directory tree, gathering file information, and saving the file details to disk (to a CSV or similar file). The following rough guide for how the classes should be laid out should be used:

Scanner - Takes the top level directory, scans for all files in the directory and returns "FileSet" class with all the files (and related FileInfo) from within the directory.

FileInfo - Stores information about the file:

- size in bytes (needs to support files as big as 64GB)

- file path

- file extension

- file name

- SHA1 hash of the file contents (string format)

- SHA1 hash of the first 1024 bytes of the file

FileSet - Stores a set of "FileInfo" classes with the ability to add/remove and iterate over the files via class functions

Some other notes:

- Should be able to call a "refresh" function on the FileInfo class to rescan that file and update it's information

- When calculating the SHA1 hash, should not read entire file into memory at once (must be able to scan really large files). Should use file streams.

- Should be able to call "save_to_disk" function on a FileSet to save that fileset's information (FileInfo objects) to disk (CSV format)

- Should be able to call "load_from_disk" function on a FileSet to load the fileset's information (FileInfo object) from disk

- Must be written in VB.net using .net framework 4.0

- Must use proper OO techniques

- Should contain in-line code documentation

- No external third-party libraries should be used

- Must be custom written, no code copied from other sources

Please ask if you have any questions.
