improve minimalWindSea definition #20
Description
change from
get_minimal_windsea(u10, v10, DT)
MinimalParticle(u10, v10, DT)
to
get_minimal_windsea(DT, u10::Number=0, v10::Number::0)
MinimalParticle(DT,u10::Number=0, v10::Number::0)
such that it can just be called with get_minimal_windsea(DT) internally,
remove explicit required definition from PW.ODESettings, WaveGrowthModels2D.WaveGrowth2D
