Proxy MSOnline Commands, Custom Environment Variables, & Enhanced Rule Parsing

Adds functionality that dynamically builds an MSOnline proxy module that wraps each MSOnline function, strips the -TenantId param, and auto-fills it so that rule evaluation can just use the Get-MsolUser or similar cmdlets and have it automatically scoped to the tenant ID

OCCAM now parses any files ending in .Rule.ps1 in the working directory while building the ruleset, rather than requiring you to place the rule in the module files

An $OCCAM PS Drive with custom environment variables is now available in the rule execution environment.

Initial Release 🎉

This is the initial version of occam published to the PowerShell gallery!
