This structure specifies pair-wise mappings of boundary loops which form the
base of a pattern feature to target faces, for each instance of the pattern
feature.

Used in:

PK_FACE_pattern_o_t

Description of fields:

'n_loops'               number of boundary loops which support the pattern
                        feature.

'base_loops'            boundary loops which form the base of pattern feature.
                        Each boundary loop must lie completely inside face.

'target_faces'          faces which specify the site of the transformed
                        instance of the pattern feature.
