Reshape version 0.7.1

Reshape is an R package for flexibly restructuring and aggregating
data.  It's inspired by Excel's pivot tables, and it (hopefully) makes
it very easy to get your data into the shape that you want.  You can find out
more at http://had.co.nz/reshape

What's new in this version?

 * A 25 page introductory vignette, also available at
http://had.co.nz/reshape/introduction.pdf, which shows some of the
many ways that you can use reshape.

 * The biggest change is that reshape now outputs regular data.frames,
which should make it easier to use them for further analysis and

 * Added a fill argument to cast which specifies what value should be
used for structural missings

Various bug fixes and completion missing features:

 * fun.aggregate will always be applied if specified, even if no
aggregation occurs

 * margins now work for non-aggregated data

 * cast now accepts a list of functions for fun.aggregate

 * very long formulas will now work in cast

 * fixed bug in rbind.fill

 * should be able to melt any cast form

Please let me know if you have any comments, questions, or something
isn't working right.
