Nlevel(gaps)

## Description

Nlevel(gaps) The gaps vector contains the energy gaps between different levels. If [1] is passed to the constructor that will result in a qbit with an energy gap of in atomic units. If an arbitraty vector [a b] is passed this results in a three-level system with energy gaps and . The input vector can be arbitrarily long and must contain positive numbers. If a level structure is needed where certain level transition are not allowed this can be realized via the setdipole(levels, value) command.
