Can refer to ParserUtil.parseTags, issue with parseTags is it currently takes in a List which only has 1 string, inside with the whole text after t/ e.g. t/ tag1 tag2 will result in a List with 1 string "tag1 tag2". This gets rejected by the validation regex for tags as it does not allow spaces
Implement a parser that will be able to call role command created in #54.
