 * @brief QmuTokenParser class constructor. Make easy initialization math parser.
 *
 * This constructor hide initialization variables, operators, character sets.
 * Use this constuctor to get tokens from formula. All formulas must be converted to external look.
 * Example:
 *
 * QmuTokenParser *cal = new QmuTokenParser(formula, osSeparator, false);
 * tokens = cal->GetTokens();
 * numbers = cal->GetNumbers();
 * delete cal;
 *
 * @param formula string with formula.
 * @param fromUser true if we parse formula from user
