Lotka Volterra Systems analizator

This program is useful to study Lotka Volterra systems. These systems are ruled by two differential equations called the Lotka-Volterra equations and also known as the predator-prey equations. They are a pair of first order, non-linear, differential equations frequently used to describe the dynamics of biological systems in which two species interact, one a predator and one its prey. This name is a bit misleading since the systems are not always composed of a predator and a prey. Indeed, in this article, we are going to study a system in which sheeps and rabits interact and compete for food. 
It is worthy to mention that this Java application is really interesting because it uses applied numerical analysis to solve the equations, that is to say, it doesn't solve the equations algebraically but instead of that, it uses the Runge Kutta method (order 4) with an step of 0.01. (this means a truly good precission for small systems).
