[Cartoweb-users] writing new plugin

The tutorial aims to be quite simple, so it assumes there is only one
search result.
To be more realistic (possibly several search results):
- modify the makeSearch() method to make it return an array of results
- add a check in filterPostRequest() to detect if there is more than 1
result
- if one result => perform the recentering as already coded
- if several results => zap the recentering and simply display a drop
down list of results (using the renderForm() method and adapted smarty
templates) in the user interface
At next page, if an item from the latter drop down list is detected
(within filterPostrequest()), perform a recentering using quite the same
mechanism than already described.
handleHttpGetRequest() is helpless in that case.
