Enhancements

Currently implementing

Use Trail activity category to store activities used as Trails. This would also be a simple way to get Trail Categories
Use "Unique Routes - Common Stretches" when resyncing differences (Resync Diff at Trail Points) time/distance differences.

Summary line: subtrails
Stretches of sub trails in the result (to get other "start points")
Resize multi graphs
Custom algorithms for smoothing (in addition to ST averaging).
Thread calculations, speed up handling for multiple cores. Will not make much difference though after other optimizations.
Insert results - compare to others. The intention is that it should be easy to paste from result services. Check a few result services, but goteborgsvarvet.com uses "Start (0 km) 00:00:00 00:00 13:33:47" and stockholmmarathon.se "5K 0.26.18 26.18 05.16 11.41 4990".
- Parse textbox
- Ignore lines where first character is # completely, truncate lines after #
- Make sure no of non commentlines match trail points (or a multiple, add several at once)
- Split fields using tab, semicolon, comma, space, trim space (in this order).
- Regexp for time: (((\d{1,2})[.:]){1,2}(\d{1,2})(,.?)). Locale dependent?
- Guess field number from data.
- If there is no data for a point, do not set it. This means that if first and last is set, the speed will be constant and if 2 and 3 only is set, the speed is even between 2 and 3 only, no other changes.
- Optional:
  - Configure name, field to parse? in # comment, using keywords?
- Some easy way to export results as activities (can be done from Edit Trail now).
- Also parse DateTime and lap times?
