Detailed Description

Generate and return the number of weeks in the specified year or the month of the year of the Gregorian calendar whose majority of days fall within the specified year or month.

The correct computation of the number of weeks in a year or a number of years requires taking into account the leap years.
Note the number of weeks with majority of days in a given year can be only 53 (for long years) or 52 (for short years).

Parameters

[in]	year	: The input scalar or array of the same shape as other array-like input arguments, of type `integer` of default kind IK, representing the year of the Gregorian Calendar.
[in]	month	: The input scalar or array of the same shape as other array-like input arguments, of type `integer` of default kind IK, representing the month of the year of the Gregorian Calendar. (optional, if present, the number of major weeks within the specified month of the year will be returned.)

Returns: countWeeks : The output scalar or array of the same shape as other array-like arguments of type integer of default kind IK, containing the number of weeks with majority (4 or more) of their days within the specified year or within the specified month of the year.

Warning: An input argument year = 0 corresponds to the historic 1 BC notation of the Gregorian calendar.
This is in accordance with the convention in astronomical year numbering and the international standard date system, ISO 8601.
The input argument month must be a number between 1 and 12.
These conditions are verified only if the library is built with the preprocessor macro CHECK_ENABLED=1.; The pure procedure(s) documented herein become impure when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1.
By default, these procedures are pure in release build and impure in debug and testing builds.

Remarks: The procedures under discussion are elemental.
