Changelog

Address situations where the geometry column has a different name. In prior versions, it was renamed. Now, we use an approach that does not require a specific geometry column name but should work regardless of what its name is.
Address CRAN warning with vignette rendering.

Prepare areal for upcoming dplyr release
Address bug with geometry collections that could cause errors in aw_intersect()
Resolve various warnings during unit tests
Change minimum version of R to 3.4
Update travis and appveyor builds

Add JOSS badges to the README and pkgdown sites
Add paper description to the README and pkgdown sites
Update CITATION file to match JOSS publication information
Update package hex logo
Remove unit testing that was cuasing problems on the noLD CRAN check of the current accepted version of the package
No changes to the software functionality

Fix issue where mixed interpolations with multiple extensive and intensive variables would get incorrect output containing two copies of the extensive results.
Patch fix to Issue 6 so that data not requiring the geometry collection fix do not get processed through that code, improving performance for those interpolations.
Updated draft of JOSS paper manuscript along with appendix code and response to reviewers added in paper/.

Fix Issue 6 - edge case where st_intersection creates a geometry collection
Fix Issue 7 - interpolation returns NA values when tid and sid are the same variable name (e.g. both are GEOID)
Fix Issue 14 - interpolation fails when the sf geometry column is not named geometry - now renamed on the fly if this is not the case
Fix Issue 16 - tibble output missing other output variables
Full draft of JOSS paper manuscript added in paper/

Added vignette titles to replace placeholders
Added examples to all exported functions
Spell check with devtools::spell_check() and RStudio’s spell check functionality for .Rmd files
Checks against winbuilder
