def map_line_shp(shp, which='all', bbox=None):
'''
Create a map object from a line shape
...
Arguments
---------
shp : iterable
PySAL line iterable (e.g.
shape object from `ps.open` a line shapefile) If it does
not contain the attribute `bbox`, it must be passed
separately in `bbox`.
which : str/list
List of booleans for which polygons of the shapefile to
be included (True) or excluded (False)
bbox : None/list
[Optional. Default=None] List with bounding box as in a
PySAL object. If nothing is passed, it tries to obtain
it as an attribute from `shp`.
Returns
-------
map : PatchCollection
Map object with the lines from the shape
This includes the attribute `shp2dbf_row` with the
cardinality of every line to its row in the dbf
(zero-offset)
