Structured Context for HfLA created data sets

### Overview
We need to have minimum standards for structured context in data sets we create and or deploy in our projects so that we can help consumers understand the context from which they come.

### Action Items
- [ ] Identify existing resources for structured context, adding each example as a link in the resources section
- [ ] Once done, remove the "TG: Gather Examples" label and add the "TG: Draft Template" label
- [ ] Create a draft template, in all the formats the data will come in (json, csv, etc.) and upload to repo as a pr in the folder structured-context
- [ ] Once done, remove the "TG: Draft Template" label and add the "TG: Create Guide" label
- [ ] Discuss plan with data science team
- [ ] Create a guide on how to use the template
- [ ] Once done, remove the "TG: Create Guide" label and add the "TG: Review Guide" label
- [ ] Review the guide with product management communities of practice
- [ ] Once done, remove the "TG: Review Guide" label and add the "TG: Leadership Review" label
- [ ] Present to Hack for LA leadership team for sign off
- [ ] Once approved, remove the "TG: Leadership Review" label and add the "TG: Place Guide" label
- [ ] Possibly create an issue template on .github
- [ ] Include link to template under resources if you add it as a template in .github
