* Fix CA1819 and CA1002 warnings
Changed the type of Languages statistic in regression tests from
Language[] to List<Language>. By doing that, the warning CA1819 was
removed but then the warning CA1002 was raised. However, this warning
was expected to be excluded from QuantConnect.Algorithm.CSharp.

Move delisting date estimation to the constructor
Using `MarketHoursDatabase` for option delisting date estimation instead USHolidays
Adding file header.
Regression algorithm added.
Use of `ExchangeHours.IsDateOpen` instead `ExchangeHours.IsDateOpen.Holidays`.
Extract values from `symbol.ID` into a local variable.
Improved Regression test
