Detailed Description

represents (multiple) answer(s) in a MenuSystem.

NAME: MenuAnswer - represents (multiple) answer(s) in a MenuSystem

DESCRIPTION:

The class is used to expand an answer given in a compact form. This answer is supposed to describe a domain and to give the gridspacing for the computations. The answer (=value) can e.g. be on the form

   "value: d=2, [0,{1&3}]x[0,1], index: [1:{20&40}]x[1:{10:100,10}]"

This answer describes two domains in 2 dim, "[0,1]x[0,1]" and "[0,3]x[0,1]". The x-direction has 20 or 40 subdivisions, while the y-direction is divided from 10 to 100 parts in step by 10. The function "expand splits the answer and put the different parts in a list where each listitem is a new list:

        d=2, [0,
        |
        

        1 - 3
        |
        

        ]x[0,1], index: [1:
        |
        

        20 - 40
        |
        

        ]x[1:
        |
        

        10 - 20 - 30 - ..... - 100
        |
        

        ]

Afterwards, this list of lists is sorted and all different combinations are put in "ans_list".
