The node matrix makes 'enquiry'type computations faster:
determining node ages, number of descendants etc. But it takes up
large amounts of memory and has no impact on adding or removing tips.
Note, trees with the node matrix can not be written to disk using the
'serialization format' i.e. with save
or saveRDS
.
The matrix is generated with bigmemory's 'as.big.matrix()'.
