CustomBase allow you to make custom base conversion in Elixir.

## Installation

Add `{:custom_base, "~> 0.2"}` to `deps` function in your `mix.exs` file.

After you are done, run `mix deps.get` in your shell to fetch and compile CustomBase.

## Examples

Lets make `Base12` module with conversion described below.

| Value | Encoding |
|------:|---------:|
| 0| 0|
| 1| 1|
| 2| 2|
| 3| 3|
| 4| 4|
| 5| 5|
| 6| 6|
| 7| 7|
| 8| 8|
| 9| 9|
| 10| A|
| 11| B|

Add macro to your module:

```elixir
defmodule Base12 do
use CustomBase, '0123456789AB'
end
```

Now your module have 2 functions `encode/1` and `decode/1`:

```
iex> Base12.encode(9)
"9"
iex> Base12.encode(10)
"A"
iex> Base12.encode(11)
"B"
iex> Base12.encode(12)
"10"
iex> Base12.decode("16")
18
iex> Base12.decode("AB")
131
```

All specs included by this library, if you want to provide your documentation,
add it after `use` call, like this:
