Version 2.0.3 released, see Changelog.txt for the changes. In the following
some major enhancements:  
   - a new lock-free task scheduling for the ParallelFor has been implemented. 
   - defined ParallelFor and ParallelForReduce classes
   - removed initial underscore in the preprocessor conditional guards in 
     order to be compliant to the C++ standard
   - added the possibility to freeze and thaw all farm threads and then 
     restart a lower number of workers in a farm having a collector thread.
     (see tests/test_stopstartall.cpp)
   - fixed possible node termination problem (in case the freezing flag was set)
   - ff_send_out_to modified in order to better work with ondemand scheduling
     policy
   - changed some int types with size_t, moved to svector whenever possible
   - more possible combinations of farm, pipeline and feedback using 
     ff_minode and ff_monode
   - better multi-input and multi-output support (ff_minode ff_monode)
