 <p>The <b>friction</b> cost parameter represents a time penalty in seconds
 of additional walking time to cross 1 meter distance.
-Friction cost can be any floating point value &ge; 0. 
+Friction cost can be any floating point value &ge; 0.
 A friction map is a required parameter; if no friction costs are desired,
 a friction map should be a raster in which all cells have a value of 0.
 <p>The <b>lambda</b> parameter is a dimensionless scaling factor of the friction cost:
