GET DIRECT CONSTANTS fails when both LHS subscripts are in the same family

[ToddFincannon]

The GET DIRECT CONSTANTS implementation fails when two LHS subscripts are both in the same family. For instance, an equation that reads a table mapping values in a dimension to the same dimension:

DimC: C1, C2 ~~|
From DimC: DimC ~~|
To DimC: DimC ~~|

g[From DimC, To DimC] = GET DIRECT CONSTANTS 'data/g.csv', ',', 'B2') ~~|

repeats the the first column of values for every column.

The algorithm that matches a model-order table subscript with a normal-order LHS subscript matches on the subscript family. This was always matching the first subscript when both of them are in the same family, as in this case. The solution is to move on to the next subscript after the first one in a family is matched.
