Major (early) revision: added augment and glance methods, which tidy data in different ways than the tidy method. This revision should be considered provisional until it is merged into the main branch.

Incorporated ggplot2's code for the fortify S3 method, which became augment.lm and tidy methods for sp, maps, and multcomp packages.

Wrote a vignette on the case example of tidying k-means clustering.

Moved fix_data_frame and the new unrowname into utilities.R.

Added NEWS file with description of changes so far.
Rearranged methods to be organized into files by class instead of by generic. Also rewrote the documentation to share tidy/augment/glance documentation for each class.

Removed vignettes from inst/doc.

Bumped version number.
Fixed typos in broom+dplyr vignette
Merge pull request #4 from dgrtwo/augment-glance
