Seperate layout visualization and power/thrust curve plots

[misi9170]

Breaking out the power and thrust curve plots form the layout plot to provide users with more flexibility. plot_floris_layout retains default behavior, but calls lower level functions. Also now allows for no labels to be printed on the layout plot (but providing turbine_names=[] to plot_floris_layout.

I think this is a big improvement @misi9170, thank you! I confirm I downloaded the code and ran examples that call the new split up functionality and it ran fine

I think though we could add just a little more to this pull request (I can help) my ideas our:

• Add in the plotting functions currently in the feature/update_layout_vis branch of FLORIS (including inter-turbine distances and wake directions) as additional options
• Make a new example (or example folder) showing different layout visualization options

Just wanting to connect this with project board and issue #34

[misi9170]

@paulf81 Sounds good, I'll work on incorporating those and creating an example.

@paulf81 I've now updated this to incorporate a wake distances/directions plot and plots for yaw offset schedules. Both can be viewed by running examples/wake_steering_design/00_analyze_single_ws_v_range.py. I believe this is now ready to be merged.

Merged!
