1/ Nettoyage+commentaires/doxygen ds Vector3d, UnitVector, LongLat,
SphereCoordSys ...
2/ Ajout de la classe angle pour faciliter les conversions rad<>deg<>arcmin
dans le fichier vector3d.h .cc
3/ nettoyage/uniformisation methodes print pour pixelmap, ajout de la
methode PixelMap<T>::Show()
4/ Ajout methodes SphericalMap<T>::HasSymThetaSlice() et
GetSymThetaSliceIndex(int_4 idx) et leurs implementations pour
SphereHEALPix et SphereThetaPhi en vue de l'optimisation du calcul
transforme Ylm
5/ Ajout methode ResolToSizeIndex ds SphereThetaPhi , SphereHEALPix et
SphereECP
