Classes("FileConfirmer","FileRequester","EzimFileResponder","FileSender") Deleted . Class "EzimSocketBinder" will now be called instead

Classes Deleted :

1. "EzimFileResponder" class
2. "EzimFileRequester" class
3. "EzimFileConfirmer" class
4. "EzimFileSender" class

New Constructors added to "EzimSocketBinder" with unique parameters
depending on whether it is a request , confirmation , file send or
response.

Since Confirmation & Respond share the same parameter . A new Parameter
of type string will be added which will determine which one it is.

The appropriate functions have been implemented to verify it .

Function doRun() has been removed as it will no longer be required.

Additional changes made to -

EzimDtxSemantics.java
EzimFileIn.java
EzimFileOut.java

to use the "EzimSocketBinder" class
