Class Description

 Full description with examples and pictures

 Default constructor

copy constructor

assignment operator

 Destructor

 Compute effective A/Z and radiation length

 Define one component of the mixture as an existing material/mixture.

 add an element to the mixture using fraction by weight

 Add a mixture element by number of atoms in the chemical formula.

 Retreive the pointer to the element corresponding to component I.

 Return true if the other material has the same physical properties
