alanwood() multiplies entries in the case of isomer mixtures about webchem

[eduardszoecs]

Thanks for reporting this!
Isomers, are always not easy to handle...
Will investigate....

This is a case when there are multiple links on the webpage.
Should be fixed now,
Please check/use/test the current version on the master branch (next cran release is planned for next year):

install.packages("devtools")
library("devtools")
install_github("ropensci/webchem")

With the new version we get:

> require(webchem)
> alanwood("S-Metolachlor", type = "commonname")$inchikey

# More then one link found! Returning first.
# 
# Querying s-metolachlor.html
# [1] "major component (S)-isomer:WVQBLGZPHOPPFO-LBPRGKRZSA-Nminor component (R)-isomer:WVQBLGZPHOPPFO-GFCCVEGCSA-N"

@Edild I confirm this is better. What would you think about returning a vector of two INCHI keys, named with the isomer description ("major component (S)-isomer")?

Good idea, I opened a new issue #42.
