Test all combinations of source and target data types (with lookups)

[rhness]

When I wrote the Assignment and Comparison Rules, I specified:

Type	Source Category	Source DTF	Target Category	Target DTF	Result
1A	String	No	String	No	String
1B	String	Yes	String	No	String
1C	Numeric	No	String	No	Numeric
1D	Numeric	Yes	String	No	Numeric
2A	String	No	String	Yes	String
2B	String	Yes	String	Yes	Date
2C	Numeric	No	String	Yes	Numeric
2D	Numeric	Yes	String	Yes	Date
3A	String	No	Numeric	No	Numeric
3B	String	Yes	Numeric	No	Numeric
3C	Numeric	No	Numeric	No	Numeric
3D	Numeric	Yes	Numeric	No	Numeric
4A	String	No	Numeric	Yes	Numeric
4B	String	Yes	Numeric	Yes	Date
4C	Numeric	No	Numeric	Yes	Numeric
4D	Numeric	Yes	Numeric	Yes	Date

But now I believe that this design will cause many compare failures between MR91 and RCA.

We should test these conditions (with lookup not-found cases) using both MR91 and RCA and verify that they compare correctly.
