Greyscale, // Greyscale is now generated from William Lenthe's ramp::gray
GreyscaleInv, // Inverted Greyscale. High signal gives light greys to white
Monochrome, // Monochrome is 'monohue': fixed hue and value; vary the *saturation* from 0 to this->sat.

MonochromeBlue, // though the blue one isn't too bad

RGB, // A kind of 'null' colour map that takes R, G and B values and returns as an RGB colour.

// the ColourMap is embedded in the workflow, such as in a VisualDataModel.

RGBGrey, // Takes RGB input and outputs a greyscale version
HSV, // A special map in which two input numbers are used to compute a hue and a saturation.

/*!
* Colour mapping
*
* \tparam T The type of the datum used to traverse the colour map. When this is a
* floating point type, then the input datum should be in the range 0.0 to 1.0. If
* an integral type, then what? For char/unsigned char then 0-127 or 0-255. When
* unsigned short then 0-MAX also. What about if unsigned int or larger? Surely not
* the full range of these? Allow a runtime choice?
*
* A simple use of a ColourMap might look like this:
*
* // Instantiate a colourmap which will convert floats (range [0,1]) into colours from the 'Plasma' colour map.
* morph::ColourMap<float> cm1(morph::ColourMapType::Plasma);
*
* // Convert floats into colours using the ColourMap::convert function:
* std::array<float, 3> clr1 = cm1.convert (0.2f);
* std::array<float, 3> clr2 = cm1.convert (0.8f);
*
* which gives two colours (clr1 and clr2) with one encoding a low value (clr1) and
* one encoding a high value (clr2).
