Get value from sourceData via a sourcePath which can be either a string or an array of strings
if sourcePath starts with $ it is treated as a jsonpath https://goessner.net/articles/JsonPath/,
that are able to map complex structures just like XPath expressions in XML
{@example $.store.book[*].title will return all titles of books in store}
otherwise it is treated as a lodash path https://lodash.com/docs/4.17.15#get
