First line of consensus map not parsed

[donovan-h-parks]

The current code structure results in the first line of the consensus map not being properly parsed. For example, the first few lines of decorate() in t2t.py are:

seed_con = consensus_map.readline().strip().split('\t')[1]
nl.determine_rank_order(seed_con)
tipname_map = nl.load_consensus_map(consensus_map, append_rank)

This aims to setup the RANK_ORDER variable within nlevel.py before calling load_consensus_map(). The issue is that the first line of code reads out the first line from consensus_map. As a result, the load_consensus_map() function misses the first taxa. I suggest that the load_consensus_map() function actually call determine_rank_order() in order to avoid this issue.
