add two methods to check for this week's parasha

[Elyahu41]

These methods were helpful to me because I just wanted to know what to read for Shnayim mikra weekly. The other getUpcomingParasha method will confuse people, in my opinion, because it will return a parasha in a week or two from now when the user might want to just know if there is a parasha this week or not.

There is also a second method for getSpecialShabbos

@Elyahu41 . Have a look at getUpcomingParshah()
