Produce a random function that is the sum of Gaussian random variables

`rpoly2`

generates a random 2nd degree polynomial (as a function)

`vars` |
a formula; the LHS is empty and the RHS indicates the variables used for input to the function (separated by &) |

`seed` |
seed for random number generator, passed to |

`n` |
the number of Gaussians. By default, this will be selected randomly. |

`rfun`

is an easy way to generate a natural-looking but random function with ups and downs
much as you might draw on paper. In two variables, it provides a good way to produce
a random landscape that is smooth.
Things happen in the domain -5 to 5. The function is pretty flat outside of that.
Use `seed`

to create a fixed function that will be the same for everybody

These functions are particularly useful for teaching calculus.

a function with the appropriate number of inputs

a function defined by a 2nd degree polynomial with coefficients selected randomly according to a Unif(-1,1) distribution.
