biscale v1.0.0

Major overhaul of biscale that includes fully refactored code, fewer dependencies, expanded functionality, and new palettes

biscale 0.2.0

• Add sf as a required instead of a suggested dependency. This resolves issues that appeared with newer releases of the tibble packages.
• Drop support for R 3.3 because CI tests now fail on this release. Minimum release of R is now 3.4.
• Add bi_scale_color() as a compliment to existing functionality. This adds the ability to create bivariate point and line maps as well.
• Add bi_pal_custom() to support custom palettes.
• Additional confirmatory CI testing for R 3.4 added to Linux (now the xenial distribution), macOS, and Windows.

biscale v0.1.2

• Add non-standard evaluation to bi_legend()
• Fix typos in README.Rmd, index.Rmd, and in bi_class.R
• Remove examples of 2x2 palettes in the bi_pal() help file to address NOTE on CRAN checks (only appeared for Solaris)
• Test biscale with new release of ggplot2 and the cowplot release candidate - no problems detected

biscale 0.1.0

• Added a NEWS.md file to track changes to the package.
• Develop bivariate mapping functionality (bi_ functions)
• Add example data set (stl_race_income data)
• Implement unit testing with both Travis and Appveyor as well as Code Coverage tracking
• Add .github community files
• Add LICENSE
• Add vignette for getting started (biscale)
• Add pkgdown site functionality
