New formulae: fasttree, glimmer3 and tRNAscan-SE

- FastTree infers approximately-maximum-likelihood
  phylogenetic trees from alignments of nucleotide
  or protein sequences. FastTree can handle
  alignments with up to a million of sequences in
  a reasonable amount of time and memory. For
  large alignments, FastTree is 100-1,000 times
  faster than PhyML 3.0 or RAxML 7.

- tRNAscan-SE detects ~99% of eukaryotic nuclear
  or prokaryotic tRNA genes. Test included

- Glimmer is a system for finding genes in
  microbial DNA, especially the genomes of
  bacteria, archaea, and viruses. With test.
