Colour the vertices of a mesh by evaluating a given gradient.

Input parameters:

1. Ms → Mesh to colour.
2. Nm → List of numbers encoding the value of each vertex.
3. Gr → Gradient to apply.
4. Mt → Scaling method for stretching the gradient to the number distribution.
   • 0 → None
   • 1 → Limits
   • 2 → Standard Deviation (68%)
   • 3 → 2-Sigma Event (95%)
   • 4 → 3-Sigma Event (99%)
   • 5 → 4-Sigma Event (99.99%)
   • 6 → 5-Sigma Event (99.9999%)

Output parameters:

1. Ms → Mesh with coloured vertices.
