Please do not modify this code without applying the changes first at "Module:Wikidata label/sandbox" and testing
at "Module:Wikidata label/testcases".

_getLabel
This function returns a label translated to desired language, created based on wikidata
Inputs:
1: item - wikidata's item's q-code or entity class
2: lang - desired language of the label
3: link_type - link style. Possible values: "wikipedia", "Wikidata", "Commons", or "-" (no link)
4: capitalization - can be "uc" (upper case), "lc" (lower case), "ucfirst" (upper case for the first letter),
"lcfirst" (lower case for the first letter)
Error Handling:
Bad q-code will result in displayed error
