Choosing the type of the expression is not trivial

[INazca]

The type of the expression was only chosen right by one user. Also it was not 100% clear to the users what they should type into the input field. It would be helpful for the users if they get suggestions or if they can only choose from a already given set of answers. This problem is not really leading to false answers, but it could cause problems with the discussion phase distribution, as almost every solution would be unique. For the UI this is only a "cosmetic" problem, but when linked to a completely functional backend it could lead to unwanted problems.

Solution:

• add a picker instead of the input field

• provide the picker with already given choices for the type

Will not be implemented for the evaluation 2 prototype due to lack of time. Still this problem needs to be fixed in the future and is important to a full stack implementation.
