Changes

Smart Projects are containers for Smart Modelling data. A Smart Project contains worksheets and Smart Models and is stored in a file with the extension "*.smp". Projects are independent from {{UBIK}} Environments, per se. That allows the user to transport and re-use smart models in different {{UBIK}} Environments. Also, a model project can be designed "offline" without working on an actual productive system. Only one project can be opened at a time. A project must be opened in order to create worksheets.
