Description

Right now this is disastrous mess, we should agree on what is the essential info and how to print it.
For example this is what the output of a FiniteGP returns:

AbstractGPs.FiniteGP{GP{AbstractGPs.ZeroMean{Float64}, TransformedKernel{SqExponentialKernel{Distances.Euclidean}, ScaleTransform{Float64}}}, StepRangeLen{Float64, Base.TwicePrecision{Float64}, Base.TwicePrecision{Float64}, Int64}, Diagonal{Float64, FillArrays.Fill{Float64, 1, Tuple{Base.OneTo{Int64}}}}}(
f: GP{AbstractGPs.ZeroMean{Float64}, TransformedKernel{SqExponentialKernel{Distances.Euclidean}, ScaleTransform{Float64}}}(AbstractGPs.ZeroMean{Float64}(), Squared Exponential Kernel (metric = Distances.Euclidean(0.0))
        - Scale Transform (s = 0.5))
x: -10.0:0.20202020202020202:10.0
Σy: [1.0e-8 0.0 … 0.0 0.0; 0.0 1.0e-8 … 0.0 0.0; … ; 0.0 0.0 … 1.0e-8 0.0; 0.0 0.0 … 0.0 1.0e-8]
)

Research direction

Start by reproducing the shown FiniteGP output and inspecting the existing display methods for AbstractGPs objects. Because the issue does not specify the essential information or target format, first agree on the intended concise representation; done means the agreed output is implemented and verified for the example.
