ltertools Version 1.1.0

There are no ERRORs, WARNINGs, or NOTEs returned by devtools::check().

• New function: make_json creates a JSON containing name/value pairs from a named vector. Optionally adds the JSON file name to the ‘gitignore’ (if one can be found in the working directory)
• New function: solar_day_info identifies sunrise, sunset, solar noon, and day length for all dates within a user-specified range at particular coordinates
• Function update: harmonize now includes new defensive warning/error checks with informative messages for likely sources of error
• Unit tests added for all functions currently in package. Likely limited impact on users except better adherence to best practice will make for a stronger package in the long run
