optimize_decay: Optimize Decay
In niallbenj/footballstats: Classify and predict football results

A function to calculate the weights for a decaying function.

1	optimize_decay(nrows, decay)

`nrows`	An integer value defining the number of rows of the data set being analysed.
`decay`	A double value that is the exponent value of the decaying function.

This function takes in the number of rows of a data set being analysed plus a decay factor which is just an exponent value, then the values of this vector are normalised to 1 so their weights total 1. (The higher the decay value, the more weighted to the closest values to the left of the vector become.)
