# Raw bond graph to structured acausal bond graph: mfile format
# The structured BG is described by four matrices:
#   junctions: describes the junctions -
#     Column 1   Index of component (see components)
#     Column 2.. Indices of bonds on junction (see jbonds)
#                  rows may be padded with zeros
#
#   jbonds:    describes the true bonds -
#     Column 1     Index of component (see components)
#     Column 2     Direction
#                    1 away from junction
#                   -1 towards junction
#     Column 3     Causality 
#                     1 stroke at arrow end
#                    -1 stroke at other end
#                     0 no stroke (ie acausal)
#     Columns 4:5  x,y coordinates of non-arrow end (in Fig)
#     Columns 6:7  x,y coordinates of arrow end (in Fig)
#
#   mbonds:    describes the modulation bonds -
#     Column 1     Index of component at non-arrow end
#     Column 2     Index of component at arrow end
#     Columns 4:5  x,y coordinates of non-arrow end (in Fig)
#     Columns 6:7  x,y coordinates of arrow end (in Fig)
#
#   components: describes the comonents -
#     Column 1     Type of component
#                    0  0-junction
#                    1  1-junction
#                    2  R component
#                    3  C component
#                    4  I component
#                    11 TF component
#                    12 GY component
#                    13 A  component
#     Column 2     Flag for explicit junction
#                    4  Explicit component (4 means text type)
#                    0  Implicit component
#     Column 3-14    fig file information (see fig documentation)
