Markers, Problems and Tasks

The module editor shows a marker whenever a problem is detected. Error markers are shown for problems that will inhibit successful execution of the module. Warning markers are shown as an indication that a problem might occur or to indicate an oversight. Of course, marked problems are listed in the task view. Markers are updated on save. In the current version, a few problems are considered. It is to be expected that the set of detected problems will grow in the future.
