To do list for package release and website build

[jflowernet]

Major items still left to do:

• Revise documentation for functions and update examples where needed
• Use examples from documentation for tests
• Update get_enviro_regions to use sampling when using NBClust package
• Run devtools::check() and sort out the no-doubt many errors and warnings

@echelleburns feel free to add to this list, these are just what came to mind. We can create separate issues for each (and there already are some for the enviro regions), but I just wanted to have a single list in one place

• Make the intersection of data with planning units more consistent across sf and raster planning grids. Currently sf features are much more extensive that the same raster feature in a planning grid.
• Check how sf_col_layer_names argument to sf_to_planning_grid is being handled - I'm pretty certain it's not doing what I wanted it to
• Standardize empty sf planning grid cells to be zero not NA
