Subject: Wrapper script to allow groups working in the build directory

On large projects, its often necessary to share the build directory between
the various users of the pipeline. To simplify the process a `for-group'
script is now added to the pipeline which is just a wrapper over the
`./configure' and `.local/bin/make' commands to make sure that the group
owner of the outputs and the permission flags are set properly.

+# Running examples:
+#
+#    $ ./for-group configure
+#    $ ./for-group make [-jN]
+#
+# This is a wrapper for the configure and Make steps designed for a group
+# of users (sharing the same group name) using this pipeline on the same
+# build directory.
+#
+# When the configuration (normally done with `./configure') and build
+# (normally done with `.local/bin/make') steps are done with this with this
+# script, all the files that are created within the pipeline have these
+# properties:
+#
+#   1) Group owner will be a special group (value of `thisgroup' below).
+#   2) The permission flags give write access to the group members.
