[bioontology-support] Problem with multiple paths to root

Hi Emily,

The path to the root is based on is_a relations. The relation between  
GO:0051726 and GO:0007049 is the relation 'regulation of cell cycle'  
and therefore is not included in the rootpath. On the other hand, the  
term melanoma from the NCI Thesaurus does contain 2 is_a parents and  
both are included in the output of rootpath call, e.g. 

Do you have a need to include relations other than is_a in the  
rootpath results?
