compute wordCloud of given annotation pairs retrieved from e.g. fetchNetwork.

1	callWordCloud(edgelist, nodelist)

`edgelist`	a data frame of annotation pairs. A source column (1st column) contains annotation terms and a target column (2nd column) contains annotated entities.
`nodelist`	a data frame of node attributes e.g. node neo4j id, node grinn id, node name, node xref.

data frame of wordcloud contains the following components:

rank = rank sort by freq

id = annotation id or annotation neo4j id

gid = annotation id or annotation grinn id

nodename = annotation name

nodelabel = annotation type

nodexref = cross references

freq = frequency of the annotation term

member = list of members of the annotation term

Return empty data frame if error or found nothing.
