  * 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.
