Definitively corrected the bug concerning memory id vs hwa id by assigning a different id to the tml event mapping artifact

Added code to associate guards to connectors linked to TMLCPChoices. Advanced in generating TML textual code for ADs

Added startName and endName for connectors in CP diagrams. Generating textual TML for a simple AD with no choices, no junctions and no nested ADs.

Corrected errors in TMLTxt generation of SD. Only need to sort actions and messages coherently with graphical design

Adding the syntax check and generation of TML text from models. Currently generating TML text in a primitive way for Sequence Diagrams

Modified TGConnectingPoint so as to update the name of source and destination instances to which a connector is linked

Substituted the generic TMLSDInstance class with 3 (derived) classes: TMLSDStorageInstance, TMLSDControllerInstance,
TMLSDTransferInstance. TMLSDInstance has been made an abstract class. In the GUI the single button for a TMLSDInstance has been
replaced by 3 buttons for each of the above classes.
