At times the genus is specified with first character and '.' rather then repeating
genus names every time. These are either synonyms or species of the same genus listed
one bellow another. To convert these names to canonical names, we need to expand the
genus name (typically) using previous entry in the list.
Usage
expand_name(fullname, shortname)
Arguments
fullname
full scientific name
shortname
scientific name with short form genus name to expand the Genus
Value
scientific name with Genus expanded using reference name provided as parameter
