New features

• New univariate model, GeneralizedGammaFitter. This model contains many sub-models, so it is a good model to check fits.
• added a warning when a time-varying dataset had instantaneous deaths.
• added a initial_point option in univariate parametric fitters.
• initial_point kwarg is present in parametric univariate fitters .fit
• event_table is now an attribute on all univariate fitters (if right censoring)
• improvements to lifelines.utils.gamma

API changes

• In AFT models, the column names in confidence_intervals_ has changed to include the alpha value.
• In AFT models, some column names in .summary and .print_summary has changed to include the alpha value.
• In AFT models, some column names in .summary and .print_summary includes confidence intervals for the exponential of the value.

Bug fixes

• when using censors_show in plotting functions, the censor ticks are now reactive to the estimate being shown.
• fixed an overflow bug in KaplanMeierFitter confidence intervals
• improvements in data validation for CoxTimeVaryingFitter
