SpectralMath

[Benjamin Jakimow]

Add SpectralMath functionality to SpectralLibrary Viewer

• modify SpectralProfiles “on the fly”
• export modified SpectralProfiles into new SpectralLibrary
• add pre-defined SpecMath functions
• allow code-defined SpecMath functions (similar to FieldCalculator)
• related to this: Field Calculator decorator functions to access SpectralProfiles

allow code-defined SpecMath functions (similar to FieldCalculator)

Or maybe better similar to imageMath!?
