Just beyond the main asteroid belt there exists a population of small objects orbiting the Sun at the same heliocentric distance of Jupiter. The combined action of Jovian and Solar gravity creates a stable dynamical haven for these objects near the so-called Lagrangian equilibrium points, in honour to the French mathematician Joseph Louis Lagrange who first demonstrated their existence and stability. ... Soon after its discovery it was realized that this asteroid is, in fact, a Mars Trojan. ...

This is the system which recieves all command inputs. it decodes inputs and selects tasks, parses parameter inputs and also runs the 'go', 'list' and 'help' commands. It does no error checking, for example to see if the parameter inputs are sensible (e.g. it does not check if an x-range has been entered as 'chicken', rather than a more understandable range of say 10,20). 2) the task decoders: icred_<taskname>.pro . ...
