This function calculates the effectiveness of temperature regulation
(E = 1 - (mean db / mean de)) as described by Hertz et al. (1993). The
thermal quality of the habitat (de) and accuracy of temperature regulation
(db) are calculated as part of this formula, so it is not necessary to run
`calculate_de`

and `calculate_db`

before running
this function.

1 | ```
calculate_E_hertz(te, tb, tset_low, tset_up)
``` |

`te` |
A vector containing operative temperatures. |

`tb` |
A vector containing body temperature measurements. |

`tset_low` |
Lower boundary of a species or population set-point range that was determined through thermal preference trials in a temperature gradient. This may be a named double vector containing the lower boundary value, or simply the value itself. |

`tset_up` |
Upper boundary of the set-point range. |
