There may be situations in which more than one of the KstDataSource plugins is willing to try and read in a given datafile, based on the filename, format, etc.

It might be advantageous to add an out parameter to the "understands" function such that a KstDataSource can indicate its level of certainty that it does understand a particular file. (e.g. UNDERSTAND_DEFINITE, UNDERSTAND_POSSIBLE, UNDERSTAND_WILL_GIVE_IT_A_GO) This parameter could then be used to select the best suited KstDataSource. All else being equal the first KstDataSource queried will be assigned the file.
