 Defines mixture OR COMPOUND IMAT as composed by
 THE BASIC NLMAT materials defined by arrays A,Z and WMAT

 If NLMAT > 0 then wmat contains the proportion by
 weights of each basic material in the mixture.

 If nlmat < 0 then WMAT contains the number of atoms
 of a given kind into the molecule of the COMPOUND
 In this case, WMAT in output is changed to relative
 weigths.
