Check confirms that every character in the factor two string is in the list in factor 1
Example 'ABCDEF' Check TestString
If testString contained 'BBB' or 'BAC' it would pass-- every character are in the factor 1 val.
If testString contained 'A123' or 'Fabcdef' it would fail and return the position 2 - where the first unacceptable character was found.
Scan looks for an exact match'
Example 'ABCDEF' Scan TestString

If testString contained '123' or 'abcdef' it would fail.
If testString contained '123ABCDEF456' it would pass and return the position 4 (where it's found)
