//! This module finds significant levels such as the freezing level and wet bulb zero level. It also
//! has functions for finding critical values at a single level, such as the maximum wet bulb
//! temperature aloft. It does not include functions for finding levels related to parcel analysis
//! and convection, those are found in the `parcel` module.
