These functions can be used with temperature and humidity sensors e.g.
DHT22 or Sensirion, to make a weather station application.
Note: pre-0.3.1 versions have incorrect heat-index.

#### 0.3.0
The formula for the **heatIndex()** was taken from https://en.wikipedia.org/wiki/Heat_index.
Since version 0.3.0 the more elaborated version of https://www.wpc.ncep.noaa.gov/html/heatindex_equation.shtml
will be used. Note: there will be performance differences.
