.SYNOPSIS
Adds a new computer target to the PowerStig database

.DESCRIPTION
Adds a new computer target to the PowerStig database to be scanned with the -SQLBatch switch on Invoke-PowerStigScan

.PARAMETER ServerName
Name of server to add

.PARAMETER SqlInstance
SQL instance name that hosts the PowerStig database. If empty, this will use the settings in the ModuleBase\Common\config.ini file.

.PARAMETER DatabaseName
Name of the database that hosts the PowerStig tables. If empty, this will use the settings in the ModuleBase\Common\config.ini file.

.EXAMPLE
Add-PowerStigComputer -ServerName DC2012Test -SqlInstance SQLTest -DatabaseName Master
Add-PowerStigComputer -ServerName PowerStigTest
