56344750a7 Fixes to Histogram 
1. Now histograms with more than 31 bins are supported (before there
   were issues with missing implementations on arrays.)
2. The items defined by `define_histogram!` are in their own module, to
   avoid issues with Rust's lack of macro hygiene for items.

a7dde93df8 More idiomatic serde support 
* Follow the suggestions from the Serde docs.
* Rename the feature from `serde` to `serde1`.
* Fix a doctest.
* Mention the feature in the README.

3a0dcafd21 Implement histograms 
In order for them to have constant size, a macro is provided to crate
the histogram type. This should be replaced by const generics once Rust
has them.

e4345f5046 impl FromIterator<&f64> and FromIterator<&(f64, f64)> 
This allows to write

    let k: Kurtosis = a.iter().collect();

instead of

    let k: Kurtosis = a.iter().map(|x| *x).collect();

but breaks type inference for code like

    let m: Min = (1..6).map(Into::into).collect();

where

    let m: Min = (1..6).map(f64::from).collect();

has to be used instead.

Fixes #8.
