polymatch\n\n### Summary \n\n- `Accept: application/json+user` will trigger `user` filter\n- `Accept: application/json+v1+user` will trigger both `v1` and `user` filters respectively.\n- `.type(['v1', 'user'])` will trigger also.\n- `.type('application/json+v1+user')` will trigger also.\n- `filter1.use(filter2)` composition works; similar to express-router.\n- `filter1.use({ key: [Function] })` json composition works.\n\n### Examples\n\n```js\nconst Polymatch = require('polymatch')\nconst filters = new Polymatch()\n\nfilters\n    .on('v1/*')\n    .use('user', (input) =\u003e {\n        // transform for version\n        input.uid = input.user_id\n        return input\n    })\n    .use('company:1089', (input) =\u003e {\n        // transform for specific customer\n        input.name = `[${input.name}]`\n        return input\n    })\n    .on('v1/result*')\n    .use(require('./filter.result.js'))\n\n// on router and handler\nconst result = this.filters\n                .on('v1/result.xml')\n                .input(rows)\n                .type(req.get('accept') || ['json'])\n                .value()\n```\n\nTry\n\n```js\n\u003e Polymatch = require('polymatch')\n[Function: Polymatch]\n\u003e f = new Polymatch\nPolymatch { targets: [] }\n\n\u003e f.on('name/v1').use('full', (input) =\u003e { input.full = input.first + ' ' + input.last; return input })\nPolymatch {\n  targets: { 'name/v1': { full: [Function] } },\n  selectedTarget: 'name/v1' }\n\n\u003e name = {first: 'Barack', last: 'Obama'}\n\n\u003e f.on('name/v1').input(name).type('application/json+not-existing-type').value()\n{first: 'Barack', last: 'Obama'}\n\n\u003e f.on('name/version-3').input(name).type('application/json+full').value()\n{first: 'Barack', last: 'Obama'}\n\n\u003e f.on('name/v1').input(name).type('application/json+full').value()\n{first: 'Barack', last: 'Obama', full: 'Barack Obama'}\n\n\n\u003e f.on('name/v1').use({simple: (input) =\u003e { input.simple = input.first[0] + input.last[0]; return input }})\n\n\u003e f.on('name/v1').input(name).type('application/json+simple').value()\n{ first: 'Barack',\n  last: 'Obama',\n  full: 'Barack Obama',\n  simple: 'BO' }\n\n\u003e f.on('name/v1').input({first: 'Barack', last: 'Obama'}).type(['full']).value()\n{first: 'Barack', last: 'Obama', full: 'Barack Obama'}\n```\n\n### Tests\n\n`mocha test.js`\n\n```\n  filter\n    ✓ payload with single mime-type string\n    ✓ payload with multiple mime-type string\n    ✓ composition with json\n    ✓ payload with multiple mime-type array\n    - payload with undefined filters\n    - payload with multiple require filters\n\n\n  4 passing (12ms)\n  2 pending\n```\n\n### Changelog\n\n- Version 1.1.0 **2017-11-22**: `from` to `input`, `to` to `type`\n- Version 1.0.2 **2017-11-21**: Go to public with MIT license.\n\n### Author\n\nJin Lee (currently working at
