> Data-flow-graph based tool to transform data.

Shortest path between `initial` and `final` is found before returning a combined function of all the transitions.

Built in protection against cycles.

## Install

````

$ npm install --save paph

````

## Usage

````javascript

const paph = require('paph');

const store = paph();

// creating a relationship

store.add({start, end, weight?, transition});

             └─┬──┘      │        └┐

             String    Number   Function

// querying relationships

store.query(initial, final); // returns a function

               └──┬───┘

                String

````

````javascript

const paph = require('paph');

const store = paph();

store.add({

    start: 'v1',

    end: 'v2',

    weight: 1,

    transition: (data) => {

        return data + '1,2 ';

    },

});

store.add({

    start: 'v2',

    end: 'v3',

    weight: 1,

    transition: (data) => {

        return data + '2,3 ' ;

    },

});

store.query('v1', 'v3')('');

//=> '1,2 2,3'
