Extrapolate from Dictionary

Source: R/Basic_CleanUp.R

Provides term mapping and extraction in one. Standardises any term according to a mapping lexicon provided and then extracts the term. This is different to the DictionaryInPlaceReplace in that it provides a new column with the extracted terms as opposed to changing it in place
