Fit wave function coefficients from a sample

1 | ```
wavefunction_fit(x, degree)
``` |

`x` |
a sample from a distribution on the reals |

`degree` |
the Hermite polynomial degree to fit |

Fits a Hermite wave function density of degree `degree`

. The values will
maximize the likelihood under the density specified under
`dwavefunction`

. A more accurate representation is obtained for a
low `degree`

if the sample is standardized to have mean zero and
variance one-half. There are diminishing returns to `degree`

greater
than 20 or so due to floating point limitations.

a numeric vector of coefficients of length `degree+1`
