Course scheduling

[fderyckel]

TODO

• We do not schedule course during the weekend and holidays??? (actually this has to be well thought out? Just make it an option. If option ticked, then remove every scheduled course if it falls into that calendar.
• Automatically fetch the default color from a js script.
• Create a report kind of tool where if you pick a course and a unit, it will tell you how many courses left you have for those units and how you already had. The time will be in a number of scheduled courses and in hours.
• In an 8 days cycle schedule, for instance, yes, one can choose (as an option) to leave out weekend and holidays as per school calendar. To do a8 days, schedule, you will need to create another scheduling tool (which will still create school schedule) but the logic is different, so let's just create another tool.
