* Org babel function for Google Maps browser

Here I simplify the previous Google maps function to simply
demonstrate the recovery of entry properties.

#+NAME: gmb
#+HEADER: :var geo_var=(or (org-entry-get org-babel-current-exec-src-block-head "geo") "4.56,7.89")
#+BEGIN_SRC emacs-lisp :results silent
  (format "geo_var is %s" geo_var)
#+END_SRC

* example of a geo location, realistic to try out
  :PROPERTIES:
  :geo:      4.56,7.89
  :END:

- call_gmb() =geo_var is 4.56,7.89=
  - interactively (type C-c on "call_gmb") visualize the current geo
    location on Google Maps with a marker and as "map" in the
    browser

* another geo location
  :PROPERTIES:
  :geo:      4.44,5.55
  :END:

- call_gmb() =geo_var is 4.44,5.55=
  - visualize another geo location as "terrain"
