Separate out calculators with special purpose in unique objects

[AndreasHNyhus]

Is your feature request related to a problem? Please describe.
It is a bit confusing that the name of the calculator determines the type of calculation it does - should be separate objects for calculators with special purpose

Describe the solution you'd like
ASV calculator, MEG calculator, TEG calculator should be unique objects
Perhaps MEG/TEG calculator could be a component calculator and define component

Agree. Will be updated to use bi-consumer pattern:
