Refactor dem2pts

[ole]

To save space and to simplify the API refactor the two functions asc2dem and dem2pts as follows:

Rename dem2pts to netcdf_dem2pts Create new function something like

def dem2pts(filename, ....):

basename, ext = os.path.splitext(filename) if ext == :

ext = 'asc' #Default

if ext == 'asc':

asc2dem(filename, ...) dem2pts(filename, ...) os.remove(basename + '.dem'

elif ext == 'dem':

dem2pts(filename, ...)
