In QT Mobility measurement range and accuracy are coupled together to form the output range

To solve the QT requirement, the mapping used is as follows
1. If symbian provides only one accuracy, use this with all the measurement ranges
2. If there are n accuracies and n measurement ranges, map linearly (n:n)
3. If there are n accuracies and n+x measurement ranges, then the mapping will be
n:n for each n measurement ranges and accuracies
