CSPBin2Txt::RunL() implements pure virtual CCmdProcessor::RunL().

It opens the input binary policy file and creates in-memory presentation of the 

policies found there. Then it stores the policies in a text file (in human readable format).

CSPBin2Txt::RunL() uses TPDStreamLoader class to load policies for the binary file

and CPDTextPersister class to store them in a text file.
