Running mulle objc clone.sh with other repositories

pertains to mulle-objc-developer 0.4.x and later

By default mulle-objc-clone.sh will clone from github.com:mulle-objc exclusively. You can pull from different repositories with -ch, -eh, -oh and different branches using -cb, -eb, -ob

mulle-objc-clone.sh -y \
-ch https://github.com/mulle-nat/ \
-eh https://github.com/john-doe/ \
-oh https://github.com/mulle-objc/ \
-cb release \
-eb experimental \
-ob master \

This will clone the common "C" libraries like mulle-thread from the release branch of mulle-nat and the strictly Objective-C related repositories from the master branch of mulle-objc. Embedded repositories like mulle-configuration will be pulled from the experimental branch of john-doe.
