Clean up the namespace. - Class names are capitalised. - Fides is now only a namespace. - The former fides class is now Fides::Manager.
Split the libary into multiple files, in general one per class.
Update to a somewhat usable version. Details about this version: - It is written in C++. - There is a fides class which implements all functionality. - It compiles to a command line version that allows you to test functionality. - It automatically creates a database in $HOME/.fides/. - It deals with trust and authorisation certificates. - It has a very simple web-of-trust implementation.
