nextMonth

Returns the HebrewMonth which follows this month, with the first being NISSAN and last being ADAR_II. If this is the last month, this will wrap around and return the first month (which would actually be part of the next year). Note: this does not account for leap years and the presence of ADAR_II - it blindly gets the next month. In order to properly determine the next month accounting for leap years and without wrapping, use getNextMonthInYear.
