Upgrading from 5.70 to 5.71

5.62) must be updated
Fixed bugs/modifications:
- the previous farfield elements (after Wolf) have been replaced by
linear infinite mapped elements
which do not handle the initial stresses neither gravity; to
overcome this difficulty the user should
define in the nearfield the initial stresses, gravity and apply
equivalent surface load on the boundary
of nearfield ; corresponding chapters in the manual have been
updated so please take a look for
more details
- the problem with loosing of units in postpro2D has been fixed
- the hiding/showing option for selected elements has been added to
the Prepro2D so now
the user can apply the surface load to a distinct continuum
element

- several improvements in the Prepro2D have been made to avoid too
often refreshing of the screen
and to increase the performance
