/**
CSPTxt2Bin::RunL() implements pure virtual CCmdProcessor::RunL().
It opens the input text policy file and creates in-memory presentation of the 
policies found there. Then it stores the policies in a binary policy file,
which may be used then by the DBMS server.
CSPTxt2Bin::RunL() uses CPDTextLoader class to load policies for the text policy file
and TPDStreamPersister class to store them in a binary policy file.
