This function constructs an update of the location and scale matrix of a normal proposal in a Metropolis-Hastings algorithm, based on earlier simulations in order to show the danger of online adaptivity.

adapump(T = 10^2, MM = 10^2)

`T` |
Number of steps between updates |

`MM` |
Number of updates, leading to a chain of length |

The function simply plots the sequence of *beta*'s along iterations, which should
collapse, as well as the range of the variability of the proposed values.
