Interface for additional force model options related to solid tides.

IncTimeDepSolidTides	Time-dependent solid tide effects: opt whether to account for the secondary contribution from certain effects of loading the crust and core.
MinAmplitude	Minimum tidal amplitude to include in the computation. Uses SmallDistanceUnit Dimension.
TruncateSolidTides	True if solid tide terms (including permanent tide) won't be included beyond the degree and order selected for the gravity model.
