Constructor methods for ColorMapping class

1 2	ColorMapping(name, colors = NULL, levels = NULL, col_fun = NULL, breaks = NULL, na_col = "#FFFFFF")

`name`	name for this color mapping. The name is automatically generated if it is not specified.
`colors`	discrete colors.
`levels`	levels that correspond to `colors`. If `colors` is name indexed, `levels` can be ignored.
`col_fun`	color mapping function that maps continuous values to colors.
`breaks`	breaks for the continuous color mapping. If `col_fun` is generated by `colorRamp2`, `breaks` can be ignored.
`na_col`	colors for `NA` values.

colors and levels are used for discrete color mapping, col_fun and breaks are used for continuous color mapping.

A ColorMapping-class object.

# discrete color mapping for numeric values
cm = ColorMapping(name = "test",
    colors = c("blue", "white", "red"),
    levels = c(1, 2, 3))

    col_fun = colorRamp2(c(0, 0.5, 1), c("blue", "white", "red")))
