"""Definitions relating to hazards classifications.

See https://github.com/inasafe/inasafe/issues/2920#issuecomment-229874044
to have a table showing you classes of each kind of hazard.

Rule of using the thresholds:
Minimum value IS NOT included, but maximum value IS included to the range.
Mathematical expression:
minimum_value < x <= maximum_value
