Unused-Alarm tags.txt - Not on any graphic but should alarm

The Unused-Alarm tags.txt file lists tags that are not on any graphic but should alarm. DBDOC puts unused tags into this category when they are not on any graphic and the following conditions hold:

for any tag - where the alarm group value is not zero
for digitals - the source DO/L block does not have S2=2, which suppresses alarming on a change
for analogs - the source AO/L block seems to have valid low and / or high limits, where valid means that, given the block range defined by its zero and span values, at least one of the limits is within span units of that range

Here are some analog examples:

zero = 0.0, span = 100.0, if either limit is between -100.0 and +200.0, we call it an alarm tag
zero = -50.0 span = 100.0, if either limit is between -150.0 and +150.0, we call it an alarm tag
zero = 0.0 span = 100.0, if both limits are above +200.0, we will not call it an alarm tag, even though the working range might be +300.0 to +400.0 and the limits set appropriately.
