Changes in version 0.15.0-99                      

  - Internal changes only. Created the BeeHive C++ template, will
    eventually move it to inst/include/ so that others can link to it.

                 Changes in version 0.15.0 (2017-11-06)                 

  - abc_cpp now checks the domain of the function.

  - New arguments parscale and fnscale added (see stats::optim)

  - New print and plot method for abc_answer class object.

                 Changes in version 0.14.0 (2016-11-17)                 

  - Added a NEWS.md file to track changes to the package.

  - New function abc_cpp written with Rcpp (roughly 50%-100% faster than
    abc_optim).

  - Both abc_cpp and abc_optim return objects of class abc_answer.

  - Objects of class abc_answer return the trace of the global optimums.
