Added typed (BLAS-like) API code examples.

Browse Source 
Details:
- Added new example code to examples/tapi demonstrating how to use the
  BLIS typed API. These code examples directly mirror the corresponding
  example code files in examples/oapi. This setup provides a convenient
  opportunity for newcomers to BLIS to compare and contrast the typed
  and object APIs when they are used to perform the same tasks.
- Minor cleanups to examples/oapi.
