mrgsolve 1.0.0

• New model syntax: THETA(n) is interpreted as THETAn in the model code;
  THETA is now a reserved word (#837, #891, #892).

• New functions collapse_omega(), collapse_sigma() and collapse_matrix()
  added which help to reshape OMEGA and SIGMA matrix objects with multiple
  blocks (#897, #900).

• New plugin nm-vars which implements NONMEM-like syntax for referring to
  compartments, differential equations, bioavailability factor, infusion
  duration and rate, and lag time (#904, #891).

• New plugin autodec which will find user-defined variables in the model
  code and automatically declare them as type double (#905, #893).

• Use ii as spacer for setting the between-dose interval when putting event
  objects in a sequence (c.f. wait) (#906, #901).

• Start deprecatingsimeta(n) and simeps(n), calls to simeta() or
  simeps() with an integer argument thus limiting the update to just a single
  ETA(n) or EPS(n); use in model code will generate warning when loading
  the model that contains the n integer value (#908, #909).
