* getJunctionsForIndirectBuses: function to find the junction. The junction is same as the stop only difference is that some
* of the stops have mulitple names we need to normalize them. It will combine the buses that are passing to the same
* junction. The function is mailnly to control the way the informatioin is displayed to the user
change: 27Dec2011
In case when either the bus from the start stop to first junction is not present or the bus from the second jucntion to the end stop is not present
I am removing that particular entry (error code6) but we can as well say in the javascript that this is the case when the user can just walk to/from the
junction .. Need to chekc on this
The error codes
0: Direct buses are found
1: only one jucntion found same as search" Bellandur" to Forum Mall
2.: One junction but then the user needs to walk to the endpoint. no need to take a bus: search string abhi yaad nahin aa rahi
3: two junctions. User needs to walk between the junction search "Bellandur" "Meanee Avenue Road"
4: No route was found ....give some junk values
5: Distance is walkable no bus to take search Bellandur and Accenture
6: Ignore this particular enetry
