Calculate Shannon entropy

This function expands a frequency vector to a vector.

1 | ```
expand(F)
``` |

`F` |
Frequency vector |

This function takes a frequency vector and expands it to a longer vector with one entr for each observation. It is reverses the `collapse`

function. A frequency vector has an entry for each position in the population. Each entry states the number of individuals in the population with this position. Here we create a vector with an entry for each individual.
