@olemis I have just raised this PR. I have tested it out of my development repo - based on the new process i documented in the readme. Once Travis has completed, assuming no issues, could you please review

@olemis appears the Travis build failed - but not certain its related to the changed I made.

Errors appear to be related to installing various packaged in Travis:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
...
An error occurred while installing nokogiri (1.10.3), and Bundler
...
Error: failed to run /Users/travis/.gem/ruby/2.3.0/bin/bundle install! The command "brew audit $(brew --repo $TRAVIS_REPO_SLUG)/Formula/*.rb" exited with 1.

The below relates to the Skycoin-cx v0.7.1 changes - which appear to have been successful

8.98s$ brew install skycoin-cx

Any ideas?

@olemis looks like its worked now. Travis is happy ;)

@olemis could you review again when you get a chance - thx.

@olemis could you review this one. I expect it should be good to go
