- * This contains macros for both VERIFY and ASSERT:

- *   VERIFY: Used when there is an error condition which is not the
- *           fault of the MCU. For example, bounds checking on data
- *           sent to the micro over USB should use this function.
- *           Another example is checking for buffer overflows, where
- *           returning from the active function causes a NAK.
- * 
- *   ASSERT: Used for error conditions that are caused by MCU firmware
- *           bugs. This is used to discover bugs in the code more
- *           quickly. One example would be adding assertions in library
- *           function calls to confirm a function's (untainted)
- *           parameters are valid.
- * 
- * The difference in behavior is that ASSERT triggers a breakpoint while
- * verify does not.
