.SYNOPSIS
High Performance Powershell Module Installation
.DESCRIPTION
This is a proof of concept for using the Powershell Gallery OData API and HTTPClient to parallel install packages
It is also a demonstration of using async tasks in powershell appropriately. Who says powershell can't be fast?
This drastically reduces the bandwidth/load against Powershell Gallery by only requesting the required data
It also handles dependencies (via Nuget), checks for existing packages, and caches already downloaded packages
