Hemispherical diffuse irradiation on a tilted surface using Perez's anisotropic sky model

## Information

This component computes the hemispherical diffuse irradiation on a tilted surface using an anisotropic sky model proposed by Perez. For a definition of the parameters, see the User's Guide.

## Revisions

- September 6, 2021, by Ettore Zanetti:
  Removed parameter `lat` as it is now obtained from the weather data bus.
  This is for IBPSA, #1477.
- November 14, 2015, by Michael Wetter:
  Added `min`, `max` and `unit` attributes for `rho`.
- June 6, 2012, by Wangda Zuo:
  Added contributions from sky and ground that were separated in base class.
- February 25, 2012, by Michael Wetter:
  Changed component to get zenith angle from weather bus.
- May 24, 2010, by Wangda Zuo:
  First implementation.
