    \brief a weapon that a player can use

    A Player has a list of weapons, that can be choosen to shoot projectiles
    (projectiles.{cc,h}) at ennemies. These weapons can be shooted sequentially
    or (if able) combined. Therefore you can choose the weapon mode = choose
    a weapon.

    A weapon is characterized by:
     o firing-rate: the initial firing rate of a weapon (1/s = Herz)
     o slowdown-factor: this is a factor d: exp(-d*x), d is element of all positive R. it determines how fast the firing-rate will slow down. if no slowdown: d=0, the bigger d is, the faster the weapon will slow down!
     o energy-consumption: this determines the energy that has to be used to produce this projectile = costs per projectile
    
    Furthermore there are some other attributes, that will help to represent a firing
    weapon in this world:
     o sound file/ressource: this is a pointer to the sound-file/ressource. however it may be represented
     o shooting animation
