[Opengrads-cooks] Draft recipe for GrADS cookbook

[hersala <he...@gm...>]

Dear Administrator:
I posted a draft recipe intended to exemplify how to manage with points and
strings when the size or the projection of the map is changed. I have
attached in "Usage and example" section the code of the script and a plot
obtained by its means.
The script has been tested several times and it works properly. The URL of
this draft recipe is:

http://cookbooks.opengrads.org/index.php?title=Recipe-xxx:_Adapting_dinamically_the_position_of_a_point_or_string_(or_both)_indicating_a_feature_in_a_map_when_the_projection_or_the_size_is_modified

It is my first contribution and surely it has points to be corrected, but I
hope it could be useful for the GrADS community users.
Thanks in advance.
