focei changes:Uses RxODE to re-arrange the problem so it does not include if/else in the model (ie. un-branched code). This allows sensitivities to be calculated in one pass saving time for multiple endpoint models and models with if/else in them.
linCmt() now uses solved systems instead of translating to ODEs.
RxODE/stan’s math headers to calculate the sensitivities of the super-positioned linCmt() solutions.nlmixr object properties accessed by $. This works for major editors including Rstudio, ESS, and Base R itself.Note this includes all the RxODE changes including dropping python.
