This LEL class handles calculation of the spectral index.
Internal
This LEL letter class is derived from LELInterface. It is used to construct LEL objects that calculate the sepectral index from 2 other LEL expression (usually images). It operates on real types (Float,Double)
This is a separate class (instead of being part of a LELFunction class), because the calculation of the spectral index requires extra variables (the frequencies) and some more complicated code.
