Junit to cover viewpoint generation

[etraisnel2]

In order to replace former manual test sheet
Design a junit that covers viewpoint generation with all options for a CDO Capella target
Shall be tested that :

in viewpoint.af plugin,
there is a models/.vp file
there is a resource reuse extension with "vp" tags in plugin.xml

In model plugin,
the EMF factory has methods taking String as parameter (ex: createMass(String name_p) )
and that we have extension code ("begin capella code")

In CDO model plugin,
there is a factory override extension
in model implementation, there are no attributes, but getters use eDynamicGet

In UI model plugin
Section are properly generated
