Ensure  array() is always defined in wpec_taxes::wpec_taxes_set_options()
In wpec_taxes::wpec_get_counry_information,  should be an array, not a boolean
Define label and country_code inside wpsc_update_location_labels, once and for all.
More once-and-for-allness.  Also, billing_state_elements with literally defined twice.
Ensure  variable is available for all execution paths in wpsc_currency_display.
Remove dead  variable in WPSC_Region constructor, also define  for all execution paths.  Needs review from @JeffPyeBrook.
Use proper saving method for WPSC_Region class.  Seems to be a copypasta issue here.  Also, need a second look at the WPSC_Region::as_array() method here.
Removed dead variable in WPSC_Region::_save_region_data()
Ensure  is always defined in WPSC_Region::_save_region_data().  Also, ensure deprecated visitor checkout meta is properly updated.  Needs review from @JeffPyeBrook
Use proper class and method in shipping helper to get country name.
Define  for all execution paths.
Explcitly declare parsed args in this function.  Though not intended for outside usage, it shouldn't break if it is used elsewhere.
Typos and doc fixes (first pass, not finished) on WPSC_Countries.  More importantly, and the change needing review from @JeffPyeBrook - uses WPSC_Data_Map::value(), instead of the non-existent WPSC_Data_Map::get(), in WPSC_Countries::get_country_isocode()
Remove unused variables from WPSC_Countries::_wpsc_countries_localizations()
Call create_country_maps properly and statically as the default callback.   is never defined.
Clean up some naming conventions, and remove unnecessary dead variable from confirmed_initialization() class.  Needs review from @JeffPyeBrook
A few minor changes to WPSC_Country:

* Typos and documentation fixes.
* Undeprecate get_data().  It's a simple alias for get_array() now.
* Define private  property.
* Define (and consistently use) private  property.  I'm not entirely sure that this is proper - as some of the code seems to assume that this should exist as both a private and public method.  Will defer to @JeffPyeBrook's review here.
A bit of overlap forgotten in the last commit.  Also, using  instead of , as  was not defined.  Over to @JeffPyeBrook for review.
