##version 1.3.0 * Added a set of functions for fitting, evaluating and plotting a range of commonly used piecewise SAR models (see help page and accompanying paper)

##version 1.2.3 * return shape algorithm fail info to model summary table * added grid_start argument option to sar_average and sar_multi * edited grid_start to ensure very small starting par values are always included * edited how grid_start works and have added a grid_n argument * changed the negative exponential model fitting process so that the z parameter can be any number rather than constrained between 0 and 1. * changed the asymptotic model fitting process so that a negative z-value cannot be returned * bug corrections in the confidence interval function, and adapting it to work with grid_start * Changing model plotting to plot smooth curves by creating 1000 fitted values using fitted parameters
