Nearly all code rewritten/refactored to streamline and reduce dependencies.
Removed support for non-standard evaluation
The contrast argument to ssm_plot() is now TRUE or FALSE instead of "none", "model", or "test". Model contrasts were removed and TRUE yields test contrasts.
Many arguments renamed (e.g., .data to data, .ssm_object to ssm_object, xy to drop_xy)
Removed ssm_plot() function in favor of ssm_plot_circle(), ssm_plot_curve(), and ssm_plot_contrast().
Renamed standardize() function to norm_standardize()
Added ssm_plot_curve()
Added CAIS and IEI instrument data
Added profile scores, results, and plotting to models with contrasts
Added PANO() function for conveniently creating scale names
All internal and external data are now data frames instead of tibbles
Rewrote all vignettes to use the updated functions, arguments, etc.
Harmonized the results and scores fields in the output of ssm_analyze()
Added many unit tests, increasing the package to 100% code coverage
Added many assertions to check for invalid input arguments
Harmonized the tidying function arguments (e.g., prefix, suffix, append)
Added print methods for degree and radian classes
Replace internal non-standard evaluation with .data references
Minor visual improvements to print and summary methods for ssm_objects

Modernize ssm_plot() function to use new tidyr syntax
Update travis CI configuration to be more explicit
Adjust the test of quantile.radian() to account for changes to %% starting in R 3.6.1 Patched
Add the name of the package to the S3 class names (e.g., circumplex_radian instead of radian) to minimize the risk of overlapping classes between packages
Add some supplementary files to the R build ignore list to avoid notes during CRAN check
Add APA-style citations to instrument documentation in addition to DOI links.
Add "Instruments" menu to package website for viewing documentation pages.
Adjust the test of quantile.radian() to account for changes to %% starting in R 4.0.0

Update the web address for Johannes in the README document.
New ssm_parameters() calculates SSM parameters (without
confidence intervals) from a vector of scores.
New ssm_score() calculates SSM parameters by row.
Added support for older versions of R (3.3.x).
