Given a list of strings and reference, return the number of strings that are similar to the reference within 3 substitions and unlimited rotations. similarStrings(reference, candidate)

Example: Reference - 'abcdefg' Candidates - 'bcdefga', 'abceeee', 'zajdmas' would return 2

Since 'bcdefga' is similar to the reference by 1 rotate 'bceeeea' is similar to to reference by 3 substitutions and 1 rotation
