* Notes for TREES DATABASE.
*
******************************

*   Move the login stuff into a sub-directory (with all the user  maintanence)

*   Maybe change user levels : 
          0- Not logged in, can view only.
          2- priv. guest (some added access?); 
          4- can add observations & photos & update trees; 
          8- Can delete stuff also;
         16- Admin user maint.

*    Return user to their page after they log in ... not just go to home page.

*    Add "admin" function (mapsymbol editing).

*    Maybe need to re-visit the whole "current photo" thing, not store as 0/1 value.

*    Photo_add.php : Need to handle adding a comment attached to the photo 
     (add field to form; clean up input (strip slashes etc) & save).

*    Current titoki install has limit of 1Mb file size .. need to fix that ***********
     php.ini set to following ... needs testing
	; Maximum allowed size for uploaded files.
	upload_max_filesize = 4M
	; Must be greater than or equal to upload_max_filesize
	post_max_size = 8M

*    Report from trial: export a list (every tree to have an observation?) in csv format.
         select * from observations by tree_id by date.  
          ?with some data from trees table included.

*    Check what's happening with photo to display following photo upload.

*    Port to mobile app (see OneNote notes)

*    Modify to include key retrieval rather than static field declarations.

*    When adding an observation .. the use of an apostrophe ("it's") prevented the record from being written.

*    Add a search function (top RH corner?) to go to a specific tree record.

*    Fix the map on the tree page so it's *NOT* a google maps.
