Hello!
I consider this utils.getViscoelasticFromSpheres simply as an auxiliary 
tool to calculate values k, c (which is a material property) from 
collision time and restitution coef (which is not a material property, 
but a property of a interaction, as me seems). What if someone wants to 
set the k,c directly? Or wants to count them in another way, for 
example, such as in the edem manual (from E and poisson)? Has this make 
sense?
