Deconstruct EPW

Description

This user object component takes an Energy Plus Weather (.epw) file path input and deconstructs the tabulated data into lists corresponding to the sample dates. These lists are grouped into branches according to their data types to reduce the complexity of the outputs. The breakdown and descriptions are taken from, http://infohouse.p2ric.org/ref/36/35818.pdf, specifically pages (32 – 43). This component was originally developed to find the average turbidity values for a specific region for use in Maxwell Renderings.
