The Rechenzentrum Garching (RZG) has been renamed into
the Max Planck Computing and Data Facility (MPCDF).

This is reflected now in the adapted headers.

In the near future, all references to the ELPA webside and
the ELPA email will also be adapted.

The user functions of ELPA are now documented with doxygen tags.
At the moment the interface of ELPA 2015.11.001 is decribed.

The documentation has step by step to be implemented for all functions
and test programms.

The examples, how to invoke ELPA from a c program have been updated.
There are now examples for ELPA1 and ELPA2 both real and complex case.
The test cases are still with less functionality than their Fortran
counter parts, they are just ment as a "proof-of-concept".

This commit is not ABI compatible, since it changes the interfaces
of some routines

Also, introduce type checking for transpose and reduce_add routines

C interfaces are now available and definied in the header
