spreadsheet version 0.6.2 has been released!

The Spreadsheet Library is designed to read and write Spreadsheet Documents.
As of version 0.6.0, only Microsoft Excel compatible spreadsheets are
supported. Spreadsheet is a combination/complete rewrite of the
Spreadsheet::Excel Library by Daniel J. Berger and the ParseExcel Library by
Hannes Wyss. Spreadsheet can read, write and modify Spreadsheet Documents.

Changes:

### 0.6.2 / 2008-12-11

* 14 Bugfixes

* Fixed a bug where #<boolean>! methods did not trigger a call to
#row_updated

* Corrected the Row-Format in both Reader and Writer (was Biff5 for some
reason)

* Populates Row-instances with @default_format, @height, @outline_level
and @hidden attributes

SST could not be saved

* Improved handling of Numeric Values (writes a RK-Entry for a Float
only if it can be encoded with 4 leading zeroes, and a Number-Entry for an
Integer only if it cannot be encoded as an RK)

* Fixes a bug where changes to a Row were ignored if they were
outside of an existing Row-Block.

* Fixes a bug where MULRK-Entries sometimes only contained a single RK

* Fixes a bug where formatting was ignored if it was applied to empty Rows

with smaller indices being set to nil.

* Read formats correctly in read_mulrk
Reported by Ivan Samsonov
Fixes that part of http://rubyforge.org/forum/message.php?msg_id=62821
which is a bug. Does nothing for the disappearance of Rich-Text
formatting, which will not be addressed until 0.7.0

* Fixes a (benign?) bug, where adding text to a template-file resulted in
a duplicate extsst-record.

* 2 minor enhancements

* Improved recognition of Time-Formats

* Improvement to Robustness: allow Spreadsheet::Workbook.new
