// Description:
// Implementation of the TEComResolverParams class.
// Provide the inline implementation of TEComResolverParams 
// TEComResolverParams allows the user to define the characteristics
// of the Interface Implementation plugin to be found.
// Default constructor of TEComResolverParams. It creates an empty uninitialized
// resolver parameter object. Such an object maybe used in calls to REComSession
// CreateImplementationL() and ListImplementationsL() methods when no specific 
// matching or filtering is required i.e. default type matching will be used.
//

Indicates that a 'generic' match is required.

Either allow Interface Implementation plugins that are specific (use no wildcards
in their registry file) or generic (use wildcards in their registry file).

In any case the user of a should NOT use wildcards in the datatype string that
is passed into this object.

Rationale:
The client that sets up the resolver is expected to know what type of data
it is handling.

Use Case:
"I have this gif to convert, but I'd prefer only gif-specific plugins" or 
"I have this gif to convert, but I'm happy with some generic image conversion
plugin".

NOT:
"I have this image I want some plugin to convert, but I don't know the type
of the image".

@pre 			The object is constructed
@post			iGenericMatch equals aGenericMatch.
