To use the extension, we must include the header, create an array of combos we
want to work with, let the plugin know we want to work with those, and then use
a special function to handle the combos:
```c++
#include <Kaleidoscope.h>
#include <Kaleidoscope-MagicCombo.h>
static const KaleidoscopePlugins::MagicCombo::dictionary_t dictionary[] PROGMEM = {
static const KaleidoscopePlugins::MagicCombo::combo_t magic_combos[] PROGMEM = {

R0C11 | R1C12 | R2C14 //right hand
},
{0, 0}
};

The combo list **must** reside in `PROGMEM`, and is a list of tuples. Each
element in the array has two fields: the left hand state, and the right hand
state upon which to trigger the custom action. Both of these are bit fields,
each bit set tells the extension that the key with that index must be held for
the action to trigger. It is recommended to use the `RxCy` macros of the core
`KaleidoscopeFirmware`, and *or* them together to form a bitfield.
The dictionary **must** end with an element containing zero values for both the

The extension provides a `MagicCombo` singleton object, with the following
methods and properties:
### `.configure(dictionary)`
### `.magic_combos`
> Configures the extension to use the supplied dictionary.
> Setting this property lets the plugin know which combinations of key presses
> we are interested in. If any of these are found active, the
> `magicComboActions()` function will be called.
### `.minInterval`
### `.min_interval`
> Restrict the magic action to fire at most once every `minInterval`
> milliseconds.
>
> Defaults to 500.
>
> Not strictly a method, it is a variable one can assign a new value to.
## Overrideable methods

action, in each scan cycle until the keys remain held. This is done by calling
the overrideable `magicComboActions` function:
