New features in version 0.11
============================

GRP parser
----------

New program item types have been introduced:

- GRAPHIC for graphical blocks
- DUMMYB it is the first block in a process
- DUMMYE it is the last block in a process

TprsCin and TprsCout classes have been removed, becouse there is very
little difference between input and output connections. New data field
called `Type' has been introduced in TprsConn class. It determines the
type of the connection and it can be `ctIn' or `ctOut' and its value is
set up by the parser.

IsEnd() and IsStart() methods have been removed from TprsConn class
becouse connections no longer determine first and last program blocks
within the process. First block MUST BE a DUMMYB block with exactly
one output connection and last block MUST BE a DUMMYE block with
exactly one input connection.
