Growth Models & asymptotic boundary 2

[lovvge]

Implement a growth model boundary with integer time (& boundary)

For a 2 dimensional version, which is complete, see #1 . What is being asked for here is a representation of the boundary , by a sequence . I am imagining for example 3,2,4,1,... means 3 across, 2 down, 4 across, 1 down. Maybe two vectors or an array with two columns could be a better data structure.

Moves require small updates at the boundaries. Possibly some kind of linked list would be a good idea.
