Java API Wrapper for the Skycoin node

[stdevMac]

Expected Behavior

Access to the Skycoin node REST API implemented in Java code or as .jar assembly

Actual Behavior

Right now this is only possible using code generated by SWIG , which requires memory handles

Specifications

• Version: 0.25.1
• Platform: all
• Subsystem: all exported API sets

Possible Solution

Generate with Swagger (share more info, please) . Beware of CSRF .

• [x] Use Skycoin node Swagger spec to generate initial Java REST API client
• [x] Add make target to automate generation in ./build
• [x] Aforementioned target should copy / merge relevant files into source code tree
• [x] README explaining the process
• [x] Mention in CHANGELOG
• [x] Patch the result Swagger-gen REST client to support specifying node address
• [x] Update package metadata
• [x] Run basic Swagger tests in Travis
• [x] Unify testing code if multiple frameworks are used across source tree
• [x] Beware of CSRF auth
