Changes in version 2020-01-16                      

  - Fixed issue where signs_format would not work if package was not
    loaded.

                     Changes in version 2019-11-25                      

  - Fixed issue #2; tests had assumed a default accuracy of 1, and
    scales 1.1.0 changed default to .1.
  - In the unlikely event a user explicitly sets format, add_plusses,
    trim_leading_zeros, or label_at_zero to NULL, functions will now
    throw an error.
  - Improved intro / summary language and updated hex logo with enlarged
    font.

                     Changes in version 2019-10-01                      

  - signs is on CRAN!
