%description
Provides a way to call the functions in 'SUNDIALS' C ODE solving library
(<https://computing.llnl.gov/projects/sundials>). Currently the serial
version of ODE solver, 'CVODE', sensitivity calculator 'CVODES' and
differential algebraic solver 'IDA' from the 'SUNDIALS' library are
implemented. The package requires ODE to be written as an 'R' or 'Rcpp'
function and does not require the 'SUNDIALS' library to be installed on
the local machine.
