Support for empty column names (as Excel is sometimes wont to put out)
Updated .gitignore for gemspecs
Messed with Rakefile so can have forked gem
Version bump to 0.5.1
Add attributes by name or alias hash
Version bump to 0.6.0
Support for named_columns, which will attempt to look up columns indices from the header row.  Default behaviour is to map the named attribute to the current ordinal cursor position, then advance the cursor.  This suppresses cursor advancement.
Version bump to 0.7.0
Support for a combination of start_at_row and named_columns (the latter always assumed a start_at_row of 1 with the headers at 0).  There's a new assumption now, that headers are always one row above start_at_row
Document named_columns
Version bump to 0.8.0
Provide access to the context, otherwise the enclosing object can't be accessed at any point. Pollutes the method_missing namespace a little further on top of mapped_attributes :(
Version bump to 1.0.0
revert custom catch for 1.8REE
