System Structure

System structure is based on my lasts projects. Here we have only one executable file "index.php". Why ? it's for security control reason (better is control small part of system than lot of folders where any one can put .php file remotly ). Now time to fill base classes like CORE, SESSIONS, USERS, DATABASE etc. We can use here PHP language skills ( pseudo reflections like in C# ), that can give more usable code to make FORMS and GRIDS in fast way (no tons of code but pure Framework).
