update babel to version 7

[achmadk]

Hello, @aichbauer. This module is useful for me to create REST API back-end. Now, I am using babel version 7 in my project. I have used this package for mapping routes easily. Unfortunately, I have this error message after updating to babel version 7.

Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version. Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel.

Can I help you to upgrade this module using babel 7?

Hello @achmadk,

thank you for your issue.

I think updating the babel version in this package would do the trick.

Would you mind creating a Pull Request to fix this issue?

[achmadk]

I have created a pull request. According to travis CI review, express-routes-mapper cannot be used in node 4.

Thank you.

I will take a look into your PR this week. I think dropping node 4 would not be a problem, since the current stable is 10, and the maintenance for node 4 ended this year in April.
