Added function to add info about Ath ortholog groups to the db
Reorganised so that getting different info is done by calling functions

currently, the only kind of info that can be retrieved is TAIR info
Added functions to get sequences and to get GTF info
first commit
modified cluster number verification so it works on incorrectly formatted clusternums
Added function to write sequences to cluster files
Added command to make pdf file with coloured branches
first commit
minor bug-fix
Added a function get_colour to return a the colour corresponding to the specified expression level
modified bin ranges so that all extremely high expression genes are the same

this allows a better spread of colours for genes with low to medium expression

first commit
Added legend, species names, title and margins and removed the sig symbol from the root

I also removed a couple of functions which weren't being used
that were left over from a previous version

I would like to add borders around the expression values, but that isn't working
properly

I would also like to add margins around the scale bar
Tree, taxon names, and expression values were scaled up so the legend would look smaller in comparison

This is my solution to the problem of the legend appearing as low-res. Now everything else
is bigger so I can just zoom out and it looks a lot better
Added code to skip clusters with too few sequences and to use fast tree building when >05 sequences

I also fixed a bug that was preventing sequences were the gene_id didn't match the cluster
number from being excluded
Modified to write all sequences before doing all alignments then doing all trees
minor bug fixes
Modified to allow 1KP sequences to be in multiple clusters
more minor bug fixes
