CCISS projections graphical outputs

We'll want to recreate the graphics that Colin produced for our paper. For the paper we had chose single site series to represent 3 different edatopic positions (B2, C4, D6). For this work we let the edatopic overlap process align the site series.

- [x] BGC maps by model, scenario, timeperiod including the ensemble. for both Subzone and Zone. Figure2 maps in CCISS paper
- [x] Historic feasibility maps
- [x] Mean change in feasibility (use Feasibility_Maps.R)
- [x] Spaghetti graph Figure 5.
- [x] Expansion/Persistence Figure 6
- [x] Feasibility persistence map Figure 7
- [ ] Overall feasibility map Figure 8.
- [ ] New. Map showing areas where some sites series will no longer support forest
- [ ] New. Compare CCISS results to Chief Foresters reference guide to flag standards that are risky given CCISS. Display on map BGCs where standards need review.
