didn't have enough precision.
Found all (most) of the gps coord to string conversions and used a constant
to insure all conversions occur with the same precision.

Following on from the recent changes to the Google Map control
to support their new v3 API, this patch introduces an alternative
map view using the Microsoft Bing v7.0 API.
Remarkably, the MS and Google APIs are extremely similar. Porting the
original code to use the MS API was relatively trivial. It would
probably make sense to combine the two charts into a single chart
with an option to select a map provider.
However, at this point to help in code maintenance they are separate
charts. It is likely that they will diverge somewhat to take advantage
of the differing features offered.
The same functionality and basic colors/lines are available in the
Bing map as the Google one. We should look at adjusting, since the
Bing map styles are more detailed and go to a much higher resolution
than Googles. As a result the current theme looks quite clumsy on
a Bing map and could be changed to use more strident colors and
take advantage of dash polylines (for example).
