random and fixed features in mutipledataset

[Emmanuel Charruau]

Hi Akshay, Hi mentors,

I see a major lack on the pedagocical use of multipledataset.
It is only working in random mode at the moment, which causes me problems.

Let me give you an example.

If I am working on a new number in falling dice, for example 7 I want
to be able to recall the other numbers but 7 more often than the other
numbers.
At the moment we will only give to the config file the following configuration :

"level" : "3",
         "objective" : qsTr("Select the number on dominoes up to 7"),
         "words" : [
            "1",
            "2",
            "3",
            "4",
            "5",
            "6",
            "7"
         ]

and apply random choices within these numbers.

We should have the choice to be able to provide exactly the numbers we
want to use through a list which will not be  random.

Example if I want to teach 7:

       "words" : [
            "7",
            "2",
            "3",
            "7",
            "5",
            "6",
            "6",
            "1",
            "2",
            "7",
            "4",
            "5",
            "6",
            "7",
            "1",
            "7",
            "3",
            "4",
            "5",
            "7",
            "7",
            "1",
            "7",
            "6",
            "4",
            "7",
            "6",
            "7",
            "7",
            "2",
            "3",
            "4",
            "5",
            "6",
            "7",

         ]

Note how often 7 is present in the list (also 6 since theoritically it
is the less well known numbers being just taught).


I would also suggest to rename "words" into StaticListDataList and
RandomDataList or whatever like this, as the keywords needs to be more
generic than words and have modes (random or fixed list)

In the activity I am writting at the moment, it will look like this:
   "words" : [
            "12345,2",
            "1245,5",
            "42,125",
            "456,85",

you can see that these data are not words.
There are also other activities where we present images and not words.

Finally if we use new keywords we can choose to keep the actual word
"words" and not break the compatibility.

Mentors, Akshay feedback is very welcomed :)

Emmanuel
