[CVS ci] pointers to struct

[Leopold Toetsch]

I've committed a first attempt to handle pointers to contained structs. 
Please have a look at src/nci_test.c:nci_pi (case 4) and t/pmc/nci_19.

The information for the contained structure is currently a property of 
that initializer element. I hope this syntax is ok.

For testing please run:
make libnci.so
