implement ability to specify specific field interaction parameters
the feature gets turned on with --ffm_interaction_matrix
then field weights can be expressed by --ffm_interaction field_id_1:field_id_2:weight
weight 0 means the interaction is fully masked out. default is weight 1.0 everywhere
field ids are sequential ids of fields as passed by field declaration parameters
WARNING: since fields are not named, this means that any change to order of field declarations requires careful adjustment of interactions too...
