This function adds evolutionary rooting information to an 'igraph' class object.

1	ogr2igraph(ogr, cogdata, g, idkey = "ENTREZ")

`ogr`	a processed object of class 'OGR' evaluated by the `groot` method.
`cogdata`	a data.frame with COG to protein mapping, with at least one gene annotation type listed in the 'rtni' object (e.g. ENTREZ gene ID).
`g`	a 'igraph' object.
`idkey`	a single character value specifying a vertex attribute name used to map 'cogdata' annotation to 'g'.

Return an updated 'igraph' object with evolutionary root information.
