For each value $at$ in the defining interval, find a bandwidth $h$ so that alpha*100 percent of data points specified in $xseq$ should be within the $(x-h, x+h)$ window. This is a utility function.

1 | ```
alpha2h(alpha, at, xseq)
``` |

`alpha` |
Smoothing parameter that for each point in the domain, use a windown width that should have alpha*100 percent of data points falling in the window. |

`at` |
a point in the x domain. |

`xseq` |
Sequence of the data points. |

A numeric value h that will be used as bandwidth in the next curve fitting process.
