* manipulation that you are told to stay away.

* 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.
*
