FileData class almost finished with methods to search into the data
base, a few still remaining.
SearchEngine enum class is used to filter the searches on the
application, if you don't understand how it works, let me know!
I'm working on the SearchEngine servlet and SearchEngine.jsp 'cause I've
never worked with them and it's being hard.
A new library has been uploaded also, I'm not sure if will use it at the
end but just in case, I'm uploading it also as a backup
