#29)

* add EXP to length2operators and check for len(curNode.value) == 1 so `**` isn't incorrectly evaluated

* change CalcNode's value field to string instead of ugly *string and switch len check to go before checking if length1operators contains the first rune/char

* go mod tidy + remove unnecessary stringer generated file + make Operator type a string for simplicity

* Fixing security issue

* add test cases for exponents

* remove nolint comment on line:45 and add nolint to 123 where we are getting unicode rep of our number
