TODO: taxize, error checking and TBMap?

[sckott]

1. Carl got errors with:

   tree <- get_phylomatic_tree(phyformat, 'TRUE', 'POST', 'new', 'FALSE')
   ((annona_cherimola:0.333333,annona_muricata:45.333336)annona:12.666667)euphyllophyte:1.000000;
   Warning message:
   In read.tree(text = z) : empty character string.
   This is a problem with the 'POST' format Phylomatic query, possibly just use GET format queries.

2. Possibly interface with Rod Page's taxonomy database 'TBMap', that already queries many taxonomic sources, including ITIS. No response from from Rod Page on email so far
