Computes the centre of mass of the tree

Description

The x coordinate of the centre of mass is defined as \frac{∑(m_ix_i)}{∑(m_i)} where m_i is the biomass of the i^{th} branch and x_i is the x coordinate of the i^{th} branch. y and z coordinates are similarly computed. The centre of mass computation excludes branches to be pruned (ie: those whose toBePruned value is set to TRUE).
