# 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)
