c1d3f12ef4 Update crossbeam-spawn.md (#496)
* Update crossbeam-spawn.md

In the latest version od Crossbeam ([docs](https://docs.rs/crossbeam/0.5.0/crossbeam/)) we have two changes:

1. Spawned closures take an argument of type `&Scope` which can be used for nested spawns.
2. The `scope` function returns a `Result` indicating whether spawned threads have been joined with success or not.

Updating the example accordingly.

* Return option from find_max

* Use split_at

a79932c9a6 Add Statistics Section With Examples (#476)
* Add Statistics Section With Examples

Add a statistics section to the cookbook!

Add an example showing how to calculate mean, median, and mode using the
Rust standard library.

Add a second example showing how to compute the standard deviation and zscore
of a set of data.

* Seek Brevity, Improve Median Example

Shorten some of the example descriptions, preferring to let the code and
Rust documentation speak for itself.

Calculate the median using an adaptation of the quickselect algorithm,
which does not mutate the original data set and should (in theory) be
slightly more performant.

Remove the unneeded statistics summary file

811331100f Correct referenced crate in percent-encode chapter (#498)

7119dc5ad9 Use provided struct in CSV tab delimiter example (#499)
The CSV encoding tab delimiter example has a struct to deserialize into.
However it wasn't used.

I've changed it to use the provided struct.
It may make more sense to remove it instead, as it isn't the point of
this example. If it turns out to be the preferred method in the pull
request process, I'll do so.

26744a77b9 Fix multiply-scalar-vector-matrix recipe (#487)
The original version was incorrect about `ndarray`'s treatment of 1-D
arrays as vectors, and it incorrectly indicated that `*` performed
matrix multiplication.

`ndarray` decides whether a 1-D array is a row vector or column vector
in matrix multiplication by whether it is on the left-hand side or
right-hand side. (The behavior matches NumPy. If it's on the left-hand
side, it's a row vector, while if it's on the right-hand side, it's a
column vector.) The original version incorrectly indicated that
calling `.reversed_axes()` on a 1-D array would make it into a column
vector. In fact, calling `.reversed_axes()` on a 1-D array has no
effect since a 1-D array has only 1 axis.

Matrix multiplication is performed with `.dot()`, not `*`. The `*`
operator performs element-wise multiplication.

cb852c17d8 Improve vector norm recipe (#486)
This removes an unnecessary allocation caused by `.mapv()` in the
original version, replaces `&Array1<f64>` argument types with
`ArrayView1<f64>` (see the new text for reasoning), and takes
advantage of the `array!` macro to make the array creation more
concise.
