function Get-DbaPfDataCollectorSetTemplate {
 <#
    .SYNOPSIS
    Parses Perf Monitor templates. Defaults to parsing templates in our template repository (\bin\perfmontemplates\)
 
    .DESCRIPTION
    Parses Perf Monitor XML templates. Defaults to parsing templates in our template repository (\bin\perfmontemplates\)
 
    .PARAMETER Path
    The path to the template directory. Defaults to our template repository (\bin\perfmontemplates\)
     
    .PARAMETER Pattern
    Specify a pattern for filtering. Alternatively, you can use Out-GridView -Passthru to select objects and pipe them to Import-DbaPfDataCollectorSetTemplate
 
    .PARAMETER Template
    From one or more of the templates we curated for you (tab through -Template to see options)
     
    .PARAMETER EnableException
    By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
    This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
    Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
