Valid expressions and semantics

Name	Expression	Type requirements	Return type	Precondition	Semantics	Post condition	Complexity
Construction	CMap<Value> cmap(min, max);	min and max are of the same Value
Obtain a color	color = cmap(value)	value is a Value	DGtal::Color	min ≤ value ≤ max	Returns a color computed after the position of value within the range [min,max]
