Tangled field guide application released - version 10.3.3

[Greg]

Version 10.3.3 of the Tangled field guide application is now available
at

http://eduneer.com/tangled/tangled-Installer.prc

Change log:
-- added logic to avoid spaces in SD card ID (as defined by MotionApps
emulator)
-- added xor option to check projection logic

Installation:
As usual, delete the old application (by using the PalmOS 'App/Delete'
menu item) before installing the new application (by running the
tangled-Installer.prc application).

Comments:
Previous versions of Tangled had three types of check projection logic
(i.e., and, or, not) because I couldn't think of any reason that xor
would be useful. However, I recently realized that checking the
difference between two lists of species is very useful. So I've added
xor to the check projection logic. Here's an interesting way to test
it.

-- Switch to the custom list and check the list of common birds
compiled by your state's bird record committee.
-- Project that list of species to the classification list..
-- Select the custom list's 'check/clear all' menu item and check the
list of common birds compiled by a nearby state's bird record
committee.
-- Project that list of species to the classification list. However,
this time check xor as the destination logic ... and be sure to
uncheck the 'reset' check projection option.

The result in the classification list will be the difference between
the two lists.
