version 3.0.0

description

• closes #24 (closed): Include the plot axis concentrations in the curves data.frame.
• closes #27 (closed): Explain the mixture model a bit better. Will link to the paper once it is published.
• closes #36 (closed): Rename effect to survival and ec to lc.
• closes #37 (closed): Rename predict_mixture() to multi_tox().
• closes #38 (closed): Include R 3.5.1 in gitlab-ci.
• closes #39 (closed): Change proportion_ca argument to proportion_sa. It now specifies the proportion of stress addition in the calculation of toxicant stress. So just calculate 1 - proportion_ca to get the new value.
• closes #40 (closed): Explicitly check R version 3.6.3 in gitlab-ci. This is for when the current rocker image moves to R 4.0.0.
• closes #41 (closed): Fix a bug in plot_stress() when which = NULL.
• closes #43 (closed): Don't let gitlab-ci run document() to increas the chance of catching mismatches between the roxygen comments and the .Rd files.
• closes #45 (closed): Rename get_log_ticks() to log10_ticks() and export it.
