Description

This program tests the option "checkDate" from the tool CSV2GDX. In the
first call of CSV2GDX, a GDX file dataBackup.gdx is written. Then, data.gdx
is created manually with different content. Finally, CSV2GDX is called again
on the unmodified CSV file with the option "checkDate" to prevent writing
data.gdx. If there would be no difference between the files dataBackup.gdx and
data.gdx, "checkDate" would have failed.
