2020-01-30mobile/dive summary: rewrite statistics codeGravatar Dirk Hohndel
There were quite a few issues with the code - clearly a complete failure of code review. - all values were '??' if a period contained no dives - imperial units were not calculated at all - significant truncation and data loss in the way totals were added as meters and minutes instead of the higher precision data that is available - several issues in striing conversion methodology, e.g. missing zero padding for minutes - missing maxSac - incorrectly calculated avgSac - incorrectly claculated number of EANx dives - hard to read code with most variables named 'temp' Signed-off-by: Dirk Hohndel <dirk@hohndel.org>

2020-01-27divesummary: add DiveSummary class to shared and backendGravatar jan Iversen
Create DiveSummary class in backend-shared and make the DiveSummary calculation results available to QML. This adds a loop over all dives (could have been done with a model, but the models available to mobile are very limited, so use the basic way). [Dirk Hohndel: renamed the results variable and combined a couple of commits] Signed-off-by: jan Iversen <jan@casacondor.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
