More cookbooks for quick start

User asks

we were wondering if you have any sample scripts that you share that e.g., load images, load annotations, train canopy delineation/extent model on image subset, run model on the entire image, assess accuracy of canopy delineation, attribute tree species based on field data collection, and assess accuracy of tree species. We can figure this out ourselves (possibly with some additional help from you), but I just thought I’d ask if you have a sample script for these tasks.

My sense is that all of this already exists within the docs, but the user started to look for it, couldn't find what they wanted and email me. @henrykironde this is part of the broader effort to improve navigation within the docs.
For each, let's point to location we would expect the user to find them in docs and figure out how to name and direct them there more cleanly.

• load images
• load annotations
• train model on image subset (i'm not sure exactly what subset means here, crop?)
• run model on entire image
• assess accuracy of model
• Multi-class point data to boxes
• Train Multi-class Model and Validate.

We could approach this as one long use case for a particular project in the example/ dir with jupyter notebooks, or we can make them tiny gists in a cookbook section. @ethanwhite thoughts?
Let's use this issue to keep track of the different places

Start by reading the existing documentation for the listed workflows and locating the example/ directory; the issue also mentions Jupyter notebooks and a possible cookbook section. Map each checklist item to the clearest existing location before deciding between one use-case project and smaller cookbook examples. Done means the workflows are discoverable through clearer documentation navigation and the scope and format are resolved.
