Description 

Author

This class can Validate and process uploaded files.

It takes an array entry of the $_FILES super-global variable for a given uploaded and file and the path of a directory to copy the uploaded file.

The class also provides a fluent interface to perform several types of validation like limiting the size of the uploaded file, or check if the file name extension or MIME type is one of the allowed, or check if a file already exists with same name in the destination directory.

A validated file is moved to the destination directory eventually renamed if there was already a file with the original name.
