The projection over the EOF in CFU_MODE now ouputs the same PC as CFU_EOF. Yeeepi git loggit log Several bug-fix to reach that point + security checks and cleaning

Weights = sqrt(cos(lat)) for ano so that covariance matrice weighted by cos(lat) + Division of EOF by weights so that the reconstruction is simply EOF * PC

EOF composition restitutes now the original field in all cases + Simplification of the convention transpose + Options to use the correlation matrix rather than the covariance matrix + Security checks + New normalization of PCs so that PC*EOF only reconstruct the original file

vertextrap.py: python script to extrapolate vertically in empty levels conserving the slope of the profiles

New directory with tools to prepare restarts from any reanalysis by interpolating/extrapolating/filling empty seas with a climatology
