Polar 2 Garmin

Disclaimer/License etc:
Ok, not going to write any disclaimer or such. If you use this... well, then you're
on your own :) Happy? Ok, carry on.

Aim:
The aim for this project is to read Heart Rate data from my AXN500 Polar watch
provided from the .HRM files that I download from it, and insert that data
into GPX files that I download from my Garmin Colorado 300 so that when I upload
those to http://connect.garmin.com they will properly show the HR data collected :)

That's all for now.

ToDo:
- Handle GPX files and insert hr data like this:

<trkpt lat="xx.750916" lon="yy.182019"><ele>243.83</ele>
    <time>2008-02-22T16:01:15Z</time>
    <extensions>
        <gpxtpx:TrackPointExtension>
        <gpxtpx:atemp>26.6</gpxtpx:atemp>
        <gpxtpx:hr>109</gpxtpx:hr>
        <gpxtpx:cad>47</gpxtpx:cad>
        </gpxtpx:TrackPointExtension>
    </extensions>
</trkpt>

<trkpt lat="xx.751120" lon="yy.181503">
    <ele>242.39</ele>
    <time>2008-02-16:01:25Z</time>
    <extensions>
        <gpxtpx:TrackPointExtension>
        <gpxtpx:atemp>26.6</gpxtpx:atemp>
        <gpxtpx:hr>112</gpxtpx:hr>
        <gpxtpx:cad>47</gpxtpx:cad>
        </gpxtpx:TrackPointExtension>
    </extensions>
</trkpt>

- Output Exersice HR min/max value
