Web GUI -- reordered the appearance of the "Attribute" selector when adding a new task and specifying which column mean what in the CSV dataset. The reordering is done due to now-present ability to simply press 'a' on the keyboard when focused on a given column to selecet it's semantics as those of an attribute. The rationale is such that there are plenty of attributes (whilst only one column for respondent, choice, alterantive and choice-set). So, now, by using TAB-a the user is able to quickly select many (otherwise more-laborious click/tap, slide-move, clik/tap) attribute columns if need be.
Web GUI changes:

*) reordered the appearance of "Attribute" selector when adding a new task (and specifying which column means what in the CSV dataset). The reordering is done due to now-present ability to simply press 'a' on a keyboard (whilst focused on a given column) to selecet it's semantics as those of an attribute. The rationale is such that there are multiple/plenty of attributes (whilst only one column for respondent, choice, alterantive and choice-set). So, now, by using TAB-a key-combo the user is able to quickly select many (otherwise more-laborious click/tap, slide-move, clik/tap) attribute columns if need be.

*) color grouping in the tasks list for the multilogit sub-tasks.

*) slightly more prominent task-delineation in task list with a different top-border in table cell for each of the tasks.
Reducing the default for the number of latent classes in the multi-logit model (in view of current hardware restrictions).
Repository belated addition of multi-logit model (the commit which commented on adding such a model had forgotten to 'git add' the relevant files)...
