Changed gtRaw2gtData so that the pepperData struct has the unit vector inclination instead of thetax and thetaz.
plotting of inclination added.
Fixed dates in changed methods.
Spheroid now takes a unit vector.
plotPeppers plots ellipseoid although the peropendicular major ellipse is missing.
plotPepper now has the same functionality as previously.
Deprecated fitFrom2Deg.
