Establish sequelize schema and integrate into existing structure

This pull request integrates the work done with @suprbh to establish a Sequelize schema for our database.  the pull request is by nature very large, and it includes the following items:

1) Create Sequelize Schema setup using dbSchema.js.  This is complete but could be refactored for modularity.

2) Restructure server to reflect the changes requested in #76.

3) Change all paths to correctly export and import modules.

All proper functions are working as expected, and grunt test ran without errors.(minus the jshint, which still requires revision).
