    -Modified script to enable passing back from the SBE
     parameters for the collectFfdc fuction
    -Added sample code for collectFfdc tags to proc_example_errors.xml
    -Added sample collectFfdc function p9_collect_some_ffdc
    -Fixed compile issue in fapi2_variable_buffer_test which was a result
     of changes to the hwp_ffdc_classes generated by the script.
