Obi lacking option to assign mass to particles

[Elegar]

Hi Jose!
Would you describe how masses distribute between particles? (I belieleve it is useful to add this info into documentation)
For example I have rope with two control points: start (mass = 1) and end (mass = 2). What it means?

• total mass of the rope is 3 and this mass proportionally distributed between all particles ?
  
• total mass is 1 + mass_of_all_particles_between_start_and_end + 2 ?
  
• another option
