Implementation of a count map in Rust. A map that holds a counter as a
value, that gets incremented each time the key is added to the map.
This implementation simply decorates the HashMap from the Rust std
library.

[Documentation](https://docs.rs/countmap)

## Usage

Add the following to your `Cargo.toml`:

```toml
[dependencies]
countmap = "0.1"
```

Next, add this to your crate root:

```rust
extern crate countmap;
```

Now you can use a count map in your code:

```rust
fn main() {
	let map = countmap::CountMap::new();
	map.insert_or_increment("foo");
}
```
