Changes in version 1.1.0                        

  - create2x2table() drug-era method has been rewritten to correctly
    track state across time points, fixing a bug where era transitions
    and ADR occurrences were not properly recorded (#1).
  - create2x2table() and create2x2tables() examples have been corrected
    to use the appropriate input types and function names (#1).
  - fit_model() now correctly references the cohort parameter
    throughout; several internal code paths were still using a previous
    parameter name, causing runtime errors for most model types (#1).
  - fit_model() examples have been corrected to use valid function and
    parameter names (#1).
  - fit_all_models() fixed a typo (parallelclusterExport ->
    clusterExport) that prevented parallel execution from working (#1).
  - Risk model examples have been corrected to use the actual exported
    function names (#1).
  - Fixed roxygen2 documentation to remove references to non-existent
    functions and resolve all R CMD check warnings and notes (#1).
