Adapter for https://github.com/kadirahq/flow-router for manul/mantra/react-apps

We implemented it to hide FlowRouter and make a transition to react-router more easy.

It also provides a function to create navigation-items that can be used to create navigations.

npm install --save @panter/manul-router

• minimal api exposes some functions of FlowRouter and adds functions to create navigation items that can be used in navgiations
• No automatic link detection unlike vanilla FlowRouter, but similar to react-reacter, simple -tags will cause a page-reload! You have to create a navItem (with createNavItem) which will have a onClick-Function that can be passed to an -tag. The automatic link detection causes problem if you want to interfer with the click, that's why we decided to disable it. This makes it easier to switch to react-router because it behaves similarly.
