+%COORDTRANSFORM - use PROJ to transform coordinates
+%
+%   Usage:
+%      [xout,yout] = CoordTransform(xin,yin,projin,projout)
+%
+%   xin,  yin : input coordinates
+%   xout, yout: output coordinates (in new projection)
+%   projin,projout: input/output projection string (PROJ)
+%
+%   This function will only work of PROJ has been installed in externalpackages

+% Check usage
