Require iconv within excel.rb, as it's a dependency
Tidy up Excel#platform_specific_iconv
Switching excel2003 to Nokogiri gets us from 35 -> 34 test failures.
Enabling the LONG_RUN tests gets us from 34 -> 38 test failures
The 48 minute GLOBAL_TIMEOUT isn't helping anyone
Drop minutes test helper, which we're no longer using
Regenerate gemspec
Whitespace
Add informative messages to some exceptions
Fixing Excel2003XML to use Nokogiri as intended gets us down to 20 test failures.
Fixing the #info method output gets us down to 19 failures
Fixing Excel2003XML#read_styles gets us down to 18 failures
Use fully-specified xpaths in Excel2003 for the presumed performance benefit
Cleanup Roo::Excel2003XML#read_styles - collapse away one path loop and make use of #at_xpath
In this test, get the reference to Roo::Google out in front of the reference to GoogleWriteError so we're sure the latter has been loaded.
Whitespace
In Excel2003XML cell reading, don't set the value unless we're reading a Data element
Collapse away two #children + name check loops into #xpath loops
