GitLab

Moved simulation related classes to folder applications\SoundFieldSimulation and respective subfolders

-added enums for parameter types, e.g.
   -soundhard (impedance, absorption)
   -null (scattering)

itaSimulationInputItem
-added frequency vector for Raven third-octave bands

itaMaterialVisualizer
-fixes according to new parameter types

-added function to convert absorption to real valued impedance

-small fixes

-boolean functions for data clases no work on multi-instances
-data classed do not overload isempty() anymore

-data type for freq data is now itaSuper for all subclasses

itaSource
-now has a general property to store wave data
-now has a source type that can be set
-according to that source type, the wave data can be set/get via dependent properties

-renamed to itaSimulationInputItem

-many boolean function now also work for multi instances
-added class to visualize material data

++documentation
- updated checks for input data

-itaMaterial for impedance / absorption / scattering
-itaSource for velocity (volume or surface) / directivity / sensitivity of speakers
