Modifying database of the Scheduler so it will work better for automatic scheduling operation. Now the scheduler database can store information for different projects. It has a table for targets that can contain targets shared by different projects (such as standard stars). For scheduling it employ a schema of observation block instead of scheduling targets. This way we can guarantee that targets that must be scheduled together are indeed. The basic input/cleaning tasks for the database are implemented in this version. It now needs work on the scheduling and sequencer algorithms. The idea is that the scheduler will only prepare the observations and the sequencer will perform the observations in the appropriate time.
