Detailed Description
This class checks a value for violation of defined limits.
If a limit violation occurs, the check() method updates the provided ParameterStatus instance. Currently the LimitAlarm supports 5 limit levels (1-5) for high and low and each can be named. These alarms are "nested": Level 5 contains Level 4 contains Level 3 contains Level 2 contains Level 1. Attempting to add high/low limits that cross boundaries will return TREK_DATA_LIMIT_VALUE_TOO_LARGE or TREK_DATA_LIMIT_VALUE_TO_SMALL.
