Fix reaxff/species

WebThis fix computes a global scalar which can be accessed by various output commands. The scalar is the spring energy = 0.5 * K * r^2. This fix also computes global 4-vector which can be accessed by various output commands. The first 3 quantities in the vector are xyz components of the total force added to the group of atoms by the spring.
