Detailed Description

Gets an array of lenght 'numberOfLabels' of lexicographically consecutive(*) capital letter strings of arbitrary lenght. (*) Successor of AA = AB, successor of NILZ = NIMA, successor of ZZZ = AAAA.

The source alphabet [A,...,Z] may be initially purged by removing unwanted letters. If B is unwanted, successor of AA is AC Unwanted strings will not appear in the returned array. If NIMA is unwanted, successor of NILZ is NIMB
