Tags should be treated as case-insensitive, since florist and Florist should mean the same thing.
-
The creation of tags via create-tag is case-insensitive,
i.e. create-tag t/aid followed by create-tag t/Aid will result in the error message: This tag already exists in the Wedlinker.

-
Tagging of the person via tag is also case-insensitive,
i.e. tag 1 t/Aid will successfully add the tag aid to the first contact

-
However, untagging the person via untag is case sensitive,
i.e. untag 1 t/Aid results in the error message Some tags were not found in the person's tag list. although the first person has the tag aid.

Firstly, this inconsistency of case sensitivity of tags is confusing for the user. Secondly, case-sensitivity in untag is unnecessary since there cannot be 2 tags with the same spelling. This only inconveniences the user.
