This is a maintenance release with the following changes meant to make the package more useful and accurate. The most important change is the addition of a "unfvector" class and a new function, as.unfvector(), that coerces all base R data classes to "unfvector" (#15). By exposing this functionality, the package can be used to coerce any data vector to a standardized representation for identical()-type comparisons, including in cases where a UNF signature is not desired or appropriate.

Other changes are described below.

New features and improvements

• Exported new function unf_equal() to better comply with R CMD check.
• Added a unfmatch element to the return value of %unf%.
• Allow %unf% to be used to compare against a character string containing a UNF signature (#16, h/t Dominik Vogel)

Behind the scenes changes

• Converted package to use roxygen documentation.
• Expanded test suite to cover raw, AsIs, and time-series vectors. (#17)
• Expanded test suite to cover %unf%. (#17)
• Expanded test suite to cover as.unfvector(). (#2)
• Converted unf() to an S3 generic, with matrix, list, and data.frame methods.
• Improved implementation of raw vector handling.
• Added base package imports to NAMESPACE. (#14)
