rsetienne/DAISIE: v4.4.0

DAISIE 4.4.0 No longer include patched version of boost/numeric/odeint/stepper/bulirsch_stoer.hpp, address the issue by passing previously uninitialised variable as boost::units::quantity. Document return type of exported Rcpp functions. Move all internal non-error printing to console message() and warning(). Add internal functions to address this. verbose variable is now numeric, varying from 0 to 3. Increasing values increase amount of messages to be printed. Change default of printing some output to golden rule of silence verbose == 0. To print again, set verbose >= 1. Remove calls to options(warn = -1) that suppress warnings in non standard way. Use suppressWarnings() where appropriate. Safely restore graphics settings after plot. Fix references in DESCRIPTION. Remove internal (unnecessary) calls to internal functions via :::. No longer use roxygen2 tag internal to document without index but use noRd instead. are_area_pars() is now internal. Replace \dontrun examples in documentation with \donttest. Speed up examples. License package C++ source files as BSL-1.0 (c) Hanno Hildenbrandt, FORTRAN files as BSL-1.0 (c) Rampal S. Etienne. Add LICENSE.note, inst/COPYRIGHTS to clarify license and copyrights.
