setupYears: Creates the AnnualResults data frame from the Daily data frame

Description

This function aggregates the results stored on a daily basis in the Daily data frame and stores the average values of these in the new data frame called AnnualResults. The "annual values" can be a full 12 months, or they can be shorter. See manual to understand paLong and paStart arguments. The simplest case, a Water Year (October through September), would have paLong=12, and paStart=10. A calendar year would be paLong=12 and paStart=1. A winter season of Dec, Jan, Feb would be paLong=3 and paStart=12
