I have some data in several excel-sheets (a 3000 lines) (csv) that I want to integrate with my model.
I want to reference those lines/fields in my excel sheets.
I've read http://confluence.jetbrains.net/display/MPSD1/Stubs
I saw that there is a concept called "stubs creater" with 2 methods modelDescriptors and updateModel.
What do they do? When are they executed? What is a ModelDescriptor?
What should I do in which method?
