1. removed nslog statements
2. changed the distance filter to 2 so that almost all movements are reported
3. disabled sleeping of the application
4. showing network activity in the status bar when the localsearch and when finding route.
5. Made modifications so that current step is highlighted in different color for the two algos.
6. Display coordinates (lat, log), Current course/required, course distance from the next coordinate, nearest distance from the route
7. Preventing the application from entering the sleep mode.
8. Archived two different algorithms to find the Last Index point, offtrack calculation.
9. The final algorithm implemented which works thoroughly well is based on brute force menthod. Basically it calculates the distance of the current location from all the path segments. The segment which gives minimum distance is highlited in yellow.
10. At this stage, it also displays displays current path segment as yellow
