[svn-r24174] Purpose: Add examples
Description: Added tutorial examples that Barbara made following the C tutorial examples. They will be configured for daily test. Platforms tested: Linux/32 2.6 (jam) - tested by running a script that compiled them with h5c++ and executing the examples; output are checked manually
