示例20: scanFormulaString

 * algorithm. If "()" appear in this recursion  it controls brackets condition. Detects two
 * pow, sqrt - additional library function in user  formula. Breaks process due to global
 * failFlag. Returns double of calculated result. In case of process faults zero result
 * is returned, and fail message is shown.

 * @param bracketsOpenedBefore  Brackets were opened before this recursion invocation */
