0.18.2

• New univariate fitter PiecewiseExponentialFitter for creating a stepwise hazard model. See docs online.
• Ability to create novel parametric univariate models using the new ParametericUnivariateFitter super class. See docs online for how to do this.
• Unfortunately, parametric univariate fitters are not serializable with pickle. The library dill is still useable.
• Complete overhaul of all internals for parametric univariate fitters. Moved them all (most) to use autograd.
• LogNormalFitter no longer models log_sigma.
