Predefined color map functions.
Receives
- `cmap`: colormap
- `logs`: vector of `CoordLog`
- `n`: number of returning ticks
and returns tuple of
1. vector of `Colorant`
2. ticks to pass to `Colorbar`, which is a Tuple of
1. vector of tick location (0 to 1)
2. vector of tick labels (strings)
Any function (or struct) which behaves like this can be used for
`lcolormapfunc` and `mcolormapfunc` kwargs of `trace2ds`.
# Types
[`ColorMapFunc`](@ref) is a supertype of all of these.
# Interface
Define these methods for the ColorMapFunc.
