factored out common functionality into DoocsTransferElement class. ReadAsync probably has wrong implementation.

added test that is sensitive on scalars and arrays (here spectra) really being read and written in a server. Currently failing because the syncutil is not worling with the new DoocsSpectrum implementation. The adapter currently really is broken

DoocsSpectrum derrives from TransferElement in the new scheme. update in server not working any more, need to also change DoocsScalar and then call readLatest on all.

*** Intermediate commit, not working *** Trying to make DoocsSpectum constuctible by name. Failing because the syncUtil is failing with decorators. Needs larger refactoring

removed direct use of CSA::ProcessArray (which is the implementation) and replaced it with NDRegisterAccessor (the base class) in the adapter. Usage in tests still pending

server based test for global writeable flag. all 'positive' tests moved from testVariableMapper to server based now. Errorhandling stays extra for the moment.

adding the current path to the linker flags before the other link pathes so an installed library is not taken, but the one supposed to be tested

added cherry picking test and improved exeption handling in case of missing attributes (not auto-tested yet)

moved xml file called text*.xml to variableTreeXml subdir to allow easier use of wildvards for test executables.

made config file to depend on the application name, and fixed execution code for the tests by gracefully quitting the doocs server thread
