usmap 0.3.0

Improvements

• Update shape files to 2017 versions.
• Improvements to fips and fips_info:
• Vectorization support (e.g. enter multiple states in fips to receive a vector of corresponding FIPS codes)
• e.g. fips(c("AK", "AL")) or fips(c("Alaska", "Alabama"))
• Mixed abbreviations and full names are also supported: fips(c("AK", "Alabama"))
• Improved warning and error messages.
• Allow data to be specified by state abbreviation or full name in plot_usmap and map_with_data (instead of just by FIPS code).
• The data frame passed to plot_usmap or map_with_data (via the data = parameter), can now be a two column data frame with columns “fips” and “values” or “state” and “values”.

Improvements
