Retrieving field-of-interest/expertise labels

[TS404]

Is there any way that get_profile(id) could be expanded to also retrieve the field-of-interest/expertise labels that profile holders assign to themselves?

I've found a way of doing this! See pull request #95

Thanks again for PR.

I've made a few additional updates to the get_profile(id) function to handle the new way of handing fields of expertise, and to return available/not_available numbers of publications (pull request #104).
I think I've correctly updated the necessary .R function file and .Rd manual file (no changes should be needed to the namespace this time).
