Custom weather data files

PVsyst offers a very general programmable interpreter for importing custom files (either weather data or measured data files).

The text file is assumed to hold one record (line) per time step.
Time steps should be hours or fractions of hours.
The Protocol defines Skipped lines, Separator, Variables to be read, Variables reading format.
It performs physical unit conversions to match the PVsyst internal standard format [MJ, MJ/m², °C, m/s].
Dates may be sequential (read or not on the file), or can have "holes".
Possibility of automatically chaining daily or monthly files with coded filenames.
