Parameters
----------
points : slice | list | str | reV.config.project_points.PointsControl
Slice specifying project points, or string pointing to a project
points csv, or a fully instantiated PointsControl object.
points_range : list | None
Optional two-entry list specifying the index range of the sites to
analyze. To be taken from the reV.config.PointsControl.split_range
property.
sam_files : dict | str | list | SAMConfig
SAM input configuration ID(s) and file path(s). Keys are the SAM
config ID(s), top level value is the SAM path. Can also be a single
config file str. If it's a list, it is mapped to the sorted list
of unique configs requested by points csv. Can also be a
pre loaded SAMConfig object.
cf_file : str
reV generation capacity factor output file with path.
sites_per_worker : int
Number of sites to run in series on a worker. None defaults to the
resource file chunk size.
append : bool

over the fout and dirout inputs.
