GRAS-22: Calculate Forage Animal Balance Without Grazing Schedule (gras_basicfab)

Calculate weighted average monthly and daily forage production for each AoA. From each monthly production, divide by the number of days in the month to get daily production.

Calculate forage supplies for each area of analysis (AoA) in the grazing system, accounting for forage partition profiles (FPPs).

Calculate monthly, yearly, and system forage animal balances for a grazing system without a grazing schedule. Forage supply and animal demand are calculated daily through all years in the grazing system.
