Changes for version 2.13
- Re-organized, and much faster, OSTN02 data look up
- format_grid now supports ... { form => 'SS' } ... to get just the grid square.
- Updated examples with proper documentation and improved plotting of maps
- Minor change in t/08out_of_range.t and t/13edge.t tests to allow for Perl with "long double" enabled. Corresponding updates to documentation. This does not affect any function; I've simply made the tests more robust. I should add that "long doubles" do not appear to benefit this module at all. The results and accuracy that I get are the same with "long doubles" but everything runs about 10% slower.
