getStart

Given the crosspoints and the sensitivity function, this function
finds where the candidate points region starts, either on the extreme of
the space of the design or the first crosspoints

Calculates D-, Ds-, A-, I- and L-optimal designs for non-linear models, via an implementation of the cocktail algorithm (Yu, 2011, <doi:10.1007/s11222-010-9183-2>). Compares designs via their efficiency, and augments any design with a controlled efficiency. An efficient rounding function has been provided to transform approximate designs to exact designs.
