added example using generated and installed example library

multiple command groups test: howto multiplex multiple commands on one stream?
don't multiplex but a select on multiple groups would be nice

include problem:
- i don't see a solution using gccxml
- a simple solution would be to have a special include file containing the neccessary includes (or 2: one for the type definitions and one for the serialization)
- another solution would be to extract the includes from the file and add them to the generated code
both solutions only work if the include paths used during compilation of a program using the library are correct[tm]
now we use the first solution

- test using valgrind
- would be nice to reduce amount of changed files
  (codegen output is often the same as the existing files - something similar to ccache
  for codegen - but not overwriting output files if they are the same)
- howto include the part after "# always the same:" in all makefiles (using the codegenerator)
  (we now use make's include)
- lib name should be group name + suffix/prefix
- the example should not get installed (but still it should show how to build a lib that gets installed :-(
  (overwriting install: doesn't work)
- at the moment make dist from within a clean source will not work
  (this is related to the nodist problem / old automake version)
  this is caused by BUILT_SOURCES not working for make dist(check?)
  and the dependency generation

  distcheck -> dist -> distdir -> DISTFILES

  all -> all-redirect -> all-am -> Makefile -> BUILT_SOURCES => bene

  => how to add dependency on BUILT_SOURCES for dist?
  the real problem is that make dist should not depend on BUILT_SOURCES
  unfortunately we can't fix this as long as we use a old automake version
- add (standalone) example using generated client library
  (=> depends on installed example)
  example consists of: the same client.cpp but provides a configure.in and Makefile.am
