we also need to store the speed of sound in water at the target location
allow Debrief to provide a doppler calculator algorithm to satc.core code (decoupling)
numerous accessors/getters
introduce an extra step, to get the Sound Speed from the user
provide the debrief Doppler calculator to the satc.core code
refactor, to let us provide bearing, not just dLat, dLong - since that allows us to use our real-world projected location objects.
need to get sound speed earlier, in order to use it
make more frequency attributes editable
include some more worked examples
use refactored freq algorithms
ensure f-nought included in doppler calc
make more frequency data editable
mature the implementation, ensure that base freq is reflected in generating preducted frequency
minor tidying, update to new DATA schema
