Class which implements a converter between SpectrumValue which are defined over different SpectrumModel.
In more formal terms, this class allows conversion between different function spaces. In practical terms, this allows you to mix different spectrum representation within the same channel, such as a device using a coarse spectrum representation (e.g., one frequency for each IEEE 802.11 channel) and devices using a finer representation (e.g., one frequency for each OFDM subcarrier).
