.. New derived data series representing an estimate of core temperature
on the basis of HR changes.
* shown on AllPlot and RideSummary
* 2 new metrics; max and avg core temperature
.. This has been based upon "Estimation of human core temperature from
sequential heart rate observations" Mark J Buller, William J Tharion,
Samuel N Cheuvront, Scott J Montain, Robert W Kenefick, John
Castellani, William A Latzka, Warren S Roberts, Mark Richter,

Allows to generate data points for manual activities from series of
work/rest intervas with distance/duration information and reps count.
It is enabled once sport is entered as Swim or Run and distance units
follows pace preferences for the selected sport.
Duration and Distance for the activity are calculated from laps information,
but it can be overridden by the user.
If LapsEditor is reactivated the lap information is preserved to allow corrections,
provided the sport is not changed.
Input method for duration is selected for simplicity and easy of input using
numeric pad, tab and enter.
