"""Initialize a line recognizer that works from character models.
The character shape model is given at initialization and needs to conform to
the IModel interface. The segmenter needs to support ISegmentLine.
The best parameter determines how many of the top outputs from the classifier
are used in the construction of the lattice. The maxcost parameter is
the maximum cost that will be assigned to a transiation in the lattice.
The reject_cost is a cost above which a character won't get added to the lattice
at all. The minheight_letter threshold is the minimum height of a
component (expressed as fraction of the medium segment height) in
order to be added as a letter to the lattice."""
