2) Created demo quantum plugin that conforms to QuantumPluginBase
Abstract class specification.
3) Demonstrated plugin registration and invocation using the demo
plugin called "QuantumEchoPlugin"
4) Created the initial file structure for a quantum CLI
5) Seeded the utils module that will contain frequently used Quantum utilities.
6) Modified the manager module to initialize and register the quantum plugin
defined in a configuration file. I have hard-coded the path to plugin for now
but this will move to a quantum.conf file.
TODO:
1) Finish up the Quantum CLI
2) Write Quantum unit tests that can be run against any plug-in for certification.
3) Create a working quantum plugin.
