Turns out you do not need to use a PSRepository, ModuleManifest, or even a subdirectory for the version number of the powershell modules. All that's required is the module filename sit in a subdirectory of the same name. Powershell will parse through the directories in $env:PSModulePath to resolve your cmdlets.
