This patch adds support for temperature and slope
across the ridefile readers.
For the most part their is no functional change
although it is now possible to view and edit these
data series in the editor.
File formats that can provide temp or slope include;
.bin, .fit, .srm, .sync, .wko
Further updates will be required to display the data
in the ride plot and histograms.
The export functions in mainwindow are getting quite
cumbersome with multiple menu options.
This patch creates a single menu option "Export.." which
allows the user to select a supported format and a filename.
To support this the ridefile reader code needed to be adjusted
to allow registered readers to declare capability to write and
use a consistent (virtual) method to do so.
By modifying the base class for ride file reader we now allow
new readers to register both read and write capability.
In some instances split ride will refuse to overwrite existing
ride files (where they have the same date/time). This patch
increments the start time by one (or more) seconds to ensure
there is no conflict.
Fixes#165.
Added a headwind data field, which is available when using
an iAero head unit, to dramatically improve the calculation
of Chung analysis for users of more recent iAero devices.
All other data files than the iAero have the headwind term set to
zero when they append a point.
RideFile data points now include lon and lat members for the longitude
degrees and latitute degrees from the source ride files. As a result
most of the RideFile readers now set longitude and latitude to zero for
each data point, except for:
* Gc Format Files - now support read/write
* Wko Format Files - now support read
* Tcx Format Files - now support read (smoothed if smart recording)
Although there are no features within GC at this point in time that use
positioning data this may change over time. Critically, as users save
files to the new GC file format whilst adding interval data it is
important that this positioning data is not discarded before new
features arrive.
