- General clean-up and commenting.
- Added comment documentation to the examples, as well as some general

macro.
- Added and renamed some files for improved integration into SDK.
- Cleaned-up documentation and code for readability.
- No longer returning XST_INVALID_PARAMETER in lieu of asserts.
- Renamed TxConfig member of the XDptx structure to Config.
