/** Configuration Manager
This class manages the configuration of Test Protocol Module operation in
relation to how to handle conflicting services.

The class provides a method for the protocol manager to call in order
to generate a decision for handling a new operation, with due consideration
of any current active operation.

Conflict decisions are taken from a Decision Table which is initialised from an
external data source during construction. The table is represented as a matrix 
of decisions organised in rows and columns, representing current operation
and new operation, respectively. The UID (unique identifiers) for the external
data items are shown in this representation of the table.

To retrieve a decision this class performs a table look-up according to the 
current operation and new operation specified by the caller. The index is
calculated using row and column values according to the operation types.
Note: the table index equates to (UID value - 1)
