#9 compound class and binding class have to be in same package

[Karl Matthias Hamel]

The Caesar compiler can not handle the situation of the
compount class and the corresponding binding class not
beeing in the same package.

There are two errors which occur in a case like this:

error:Cannot find constructor
"StudentContactGraphColoring$ThreadMapper" with
matching parameters [JLS 15.12]

error:Cannot find constructor
"StudentContactGraphColoring$MultiInstanceContainer"
with matching parameters [JLS 15.12]

It may be, that the two missing constructors do not get
the needed "public" property when they are created.
