VMatrix the reindexes the target fields of a source VMatrix, according to the getValues(row,target_col) function, where row contains the values of a row of the source VMatrix, and target_col is the column index of (one of ) the target field.
This is useful when the possible target values change from one row to another. This way, target values will range from 0 to getValues(row,target_col).length()-1. The source VMatrix must be able to fournish the Dictionary objects for the target fields.
