Polar to TCX convertor

	XML file:	Polar XML file as exported from the Polar Personal Trainer website. Note that Polar files with interruptions are not supported as the Polar Personal Trainer does not output the necessary details on the interruption into the XML file.
	Timezone:
	GPX file (Optional):	Leave blank if you do not wish to add GPS-information. Note that multi-track GPX files have not yet been tested and will probably not work as intended.
	Time offset (in seconds):	Time in seconds to add to all time information in the Polar file in order to align it to the GPX data. This needs to be integer and can be positive or negative.
	Polar Speed/distance scaling factor (default 1.0):	Multiply speed/distance measures in the Polar XML file by a constant scaling factor. This can for instance be useful for badly calibrated footpod's. Input must range from 0 to 10.
