TypeScript SDK examples

[dfarr]

Our adopters will need example applications.
Populate the examples-ts repository with examples.
The examples should be broken up into two categories:

• by feature
• by use-case

By feature examples are short, and to the point, mainly showcasing the api usage and providing working code that can be copied.

By use case examples are more in-depth and provide a minimal functional use case, tying together as many APIs and Application Nodes needed to satisfy the use case.
