Parser > distinctive head-sign finder > try N/S E/W

[mmathieum]

• use center of each direction's stops to check if it might be a match for N/S or E/W
• check that (?)70% of stops for each direction confirm the split
• replace or append/prepend N/S E/W to existing trip head-sign (if route long name == trip head-signs ??)
• (?) better than using the last stop name as direction head-sign?
• agency setting for overriding/trying fist E/W N/S for direction head-signs?
