easier axis renaming

[gdkrmr]

For distance matrices or correlation matrices you need an easy way to "duplicate" axes, something like this:

PcaAxis = CABLAB.Cubes.Axes.CategoricalAxis{String, Symbol("PCA axes")}
makePcaAxis(n::Integer) = PcaAxis(["PCA_" * @sprintf("%03d", i) for i in 1:n])
function outPcaAxes{A <: CABLAB.CubeAxis}(axis::Type{A} = VariableAxis, i::Int = 1)
    ( (cube, pargs) -> makePcaAxis(length(CABLAB.getAxis(axis, cube[i]))), )
end

If you have a pca axis as above for two sets of variables and want to make a correlation you have to do something like this:

BioPcaAxis = CABLAB.Cubes.Axes.CategoricalAxis{String, Symbol("Bio PCA axes")}
makeBioPcaAxis(n::Integer) = BioPcaAxis(["Bio_PCA_" * @sprintf("%03d", i) for i in 1:n])
function outBioPcaAxes{A <: CABLAB.CubeAxis}(axis::Type{A} = VariableAxis, i::Int = 1)
    ( (cube, pargs) -> makeBioPcaAxis(length(CABLAB.getAxis(axis, cube[i]))), )
end

AtmPcaAxis = CABLAB.Cubes.Axes.CategoricalAxis{String, Symbol("Atm PCA axes")}
makeAtmPcaAxis(n::Integer) = AtmPcaAxis(["Atm_PCA_" * @sprintf("%03d", i) for i in 1:n])
function outAtmPcaAxes{A <: CABLAB.CubeAxis}(axis::Type{A} = VariableAxis, i::Int = 1)
    ( (cube, pargs) -> makeAtmPcaAxis(length(CABLAB.getAxis(axis, cube[i]))), )
end

and then for changing the actual axes:

map!(x -> typeof(x) == RMSE.PcaAxis ? makeBioPcaAxis(length(getAxis(RMSE.PcaAxis, bio_global_pca_cube))) : x, 
     bio_global_pca_cube.axes)
map!(x -> typeof(x) == RMSE.PcaAxis ? makeAtmPcaAxis(length(getAxis(RMSE.PcaAxis, atm_global_pca_cube))) : x, 
     atm_global_pca_cube.axes)

some easy way to change the axes would be appreciated, e.g.:

BioPcaAxis = prefix_axis(PcaAxis, "Bio")
AtmPcaAxis = prefix_axis(PcaAxis, "Atm")
change_axis!(bio_global_pca_cube, PcaAxis, BioPcaAxis)
change_axis!(atm_global_pca_cube, PcaAxis, BioPcaAxis)

Bumping this issue, because output axes from cubefittable have a generic name at the moment. Would be the easiest way to implement a renaming function.

This should be solved now? Can you try renameaxis!(cube,"Time"=>"Newtime")
