cepiweek: Continuous Epidemiological Week Indexing for Time-Series Analysis

Provides a simple algorithm to generate a continuous epidemiological week index from date variables in a data frame. Weeks are computed as sequential 7-day intervals aligned to Mondays, starting from the earliest observed date or from a user-supplied start date. They do not reset at calendar year boundaries and are not ISO 8601 nor MMWR calendar weeks. Missing or non-convertible dates are returned as NA instead of stopping the computation. The approach is intended for epidemiological modeling and time-series analysis where temporal continuity is required.
