05-08-12 2D Option

Updated some test runs in the Sample directory.

Created a new folder (Samples\2D_MultiRun) that includes 3 files for simple test of automatic 2D simulation. The example when creating a multiple run document from the Sim-file  in the directory a run of 5 vertical columns will be made that are directly linked to each other. Lateral input to the first run will be read from the file COUP_52 but later lateral input will be read from adjacent runs of the models when simulation are made in multirun mode.         PEJ
