Whether to find introns per gene or transcript.
nb_cpu: int, default 1
How many cpus to use. Can at most use 1 per chromosome or chromosome/strand tuple.

"""
Prepare ROC-like plot showing distribution of coverage across genome.
This method prepares a plot that aims to visualise the fraction of
the genome that is reflected at different levels of coverage. The
genome is split into windows of size tile_size and coverage averaged
across these windows. The maximum depth is calculated and the
coverages are binned into bins bins. The data is then prepared so
that 100% of the genome is covered at 0 depth going to 0% of the
genome at max_depth+1 depth.
Parameters
----------
max_depth: int
The maximum depth to render within the plot.
# TODO: this looks borked
bins: int
The number of bins to present in the plot. This is really an
aesthetic thing only.
tile_size: int
The tile size to summarise depths at. The default is 10.
boundaries_of_interest: list of ints
This will direct the plotting of lines to show the positions where
specific coverages are reached. The default is [10, 100].
**kwargs: **kwargs
can provide a number of possible options to the Flounder class in
the background that may be used to alter the plot dimensions,
bokeh tools and plot rendering options.
