• [x] collections: Basic examples of creating and deleting collections.
• [x] insert: Working with different types of inserts using both NewDocument and NewDocumentOf.
• [x] sort: A few examples for sorting, integers, UNIX dates, etc.
• [x] update & delete: Handling different types of update for both single and all documents.
• [x] import & export: Examples for the upcoming https://github.com/ostafen/clover/issues/16.
• [ ] engines: How to use the config.go functions & options and choosing different engines.

Data examples have been taken from /test/data/todos.json

I haven't been able to add examples for engines as I am not certain how this feature works.

I've also just noticed that the ImportCollection and ExportCollection have been added to the main branch. Should I pull and merge the new changes first then add those examples to the PR or will that affect the PR history?

Do not worry about the PR history, because I can squash the commits before merging the PR. So feel free to merge the new changes on your branch :=)

@ostafen I've pushed the new example for exporting and importing collections. I've also updated the description. Let me know if there's something I've missed out

Thank you. I think we can include samples about config.go in a second moment, since, for now, the most relevant one is the InMemoryMode, which has been shown in the Import/Export example.
