Entry point for app for organization

Summary of changes
Changes introduced in this pull request:

• Best not to have the root crate as the binary to allow easier and more clear references to other crates within our project, but completes Entry Point #19
• Sets up install command to install to cargo bin to be used easier than building and running from target directory

Just wanted this setup to make a few other things easier in the near future.
