v2.0.17

• Added ability to query R user functions in a rxode2 model (will
  force single threaded solve)

• Moved core rxFunParse and rxRmFunParse here so that C and R user
  function clashes can be handled

• Model variables now tracks which compartments have a lag-time
  defined

• For compartment with steady state doses (NONMEM equivalent SS=1,
  SS=2), an additional tracking time-point is added at to track the
  time when the lagged dose is given. As an upshot, the lagged dose
  will start at the steady state concentration shifted by + ii - lag
  in rxode2 (currently for ode systems only)

• This release calculates non bio-availability adjusted duration for
  all rates instead of trying to figure the rate duration during
  solving.

• Make double assignment an error, ie a <- b <-

• NA times are ignored (with warning)

• Steady state bolus doses with addl are treated as non steady state
  events (like what is observed in NONMEM)

• Timsort was upgraded; drop radix support in rxode2 structure

• etTrans now supports keeping logical vectors (with the appropriate
  version of rxode2).

• Security fixes were applied as requested by CRAN
