Maintenance of the project

[hardselius]

Hello!

First off, I think this project is great and it's a fantastic tool for building integration tests of json apis.

It looks like the project has not been maintained for quite a while. I'm interested in pitching in or even taking over. There are at least two PRs that I'm dying to get merged because they have been super useful in my tests.

Really need the epsilon for floats comparison :(

For anyone coming here, I forked the project and I intend to maintain it. I will happily accept contributions.
