* This file describes materials and mixtures to be used by GEANT
*
* For individual elements the format is
*   name 1 density material_number
*	element_name A Z radiation_length
*
* For mixture the format is
*   name number_of_elements density material_number
*     element_name A Z weight
*
* where name is a unique string describing this material
* density is the material density in grams/cm^3
* material_number is the number by which the user refers to this material
* element_name is a string describing the element
* A is the atomic number in amus
* Z is the charge of the element in |e|
* weight is the relative weight of the materials with respect to the others
*	if element_number is negative weight is a number ratio
* radiation_length is in g/cm^2
