Ant design global styles are leaked through this package

[Jokinen]

Hello again!

I don't know if you have noticed, but Ant design leaks some global style definitions such as reset styles. There's quite an extensive issue about it in antd's repository which gives some background:
ant-design/ant-design#4331

The problem is that this library imports directly from within the index of the antd package:

react-big-scheduler/src/index.js

Lines 1 to 4 in 49ea0b3

	import React, {Component} from 'react'
	import {PropTypes} from 'prop-types'
	import {Row, Col, Icon, Radio, Popover, Calendar} from 'antd'
	import EventItem from './EventItem'

Which means that the global reset styles are applied on all projects which use this library. For instance with our project links would get coloured unexpectedly as we are using styled-components and have only a few global styles.

I've opened a PR (#19) for this issue which proposes a quite hacky fix. Hopefully it can act as a starting point for resolving this issue.

I'm hopeful that the fix will work! We used it with a forked version for a single proof-of-concept project, but didn't need to do a lot of builds
