Displaying short courses after their execution has started

[cecepasinechka]

Currently, Prof. Strnad's course is still being shown because, at the time, only executionStartDate was set to the execution start, and not the date in the Jekyll template. This was done so that students could still view the schedule and short course. However, this approach of showing with no set end date isn't ideal. Also, registration should close a set amount of time before the executionStartDate (should professors specify that?).

Ideas:

• Add an executionEndDate, so the course continues to be displayed under krajsa-izobraževanja until that date, but with the subscription disabled
• Stop displaying the course once it starts, with students registering beforehand and receiving updates via email from the professor
• Set cType to 2;
  1 would mean subscriptions in progress, 2 would mean execution in progress. With status 2 the course is not shown on the catalog.krajsa-izobrazevanja but only on krajsa-izobrazevanja for an x amount of days after the executionStartDate. Alternatively, the course can be shown on catalog.krajsa-izobrazevanja, with status 2 displaying subscriptions for this course are closed.
