Maintenance release for CRAN requirements.
Use extract_parameter_set_dials() instead of parameters() to get parameter sets.
Removed some pillar-related S3 methods that currently live in tune.
tune_sim_anneal() only overwrites tuning parameter information when they originally contain unknowns.A check was added to make sure that lme4 or BradleyTerry2 are installed (#8)
Added pillar methods for formatting tune objects in list columns.
Fixed bug in random_integer_neighbor_calc() to keep values inside range (#10)
tune_sim_anneal() now retains a finalized parameter set and replaces any existing parameter set that was not finalized (#14)
A bug in win/loss racing was fixed for cases when one tuning parameter had results that were so bad that it broke the Bradley-Terry model (#7)
