1. move PRACTIP2Interface to P2Runtime
   make it as a default component
   make the handlers as part of the default handlers
  
   complete the write/clear etc.

2. use writeline/readline instead of readString/writeString
   for the storing and retrieving the tuples from the files

3. TupleHandler forks a new thread/or maintain a thread pool to
	  handle the practiReadAndWatch tuple calls from P2.
