function Set-SPRConfig {
<#
.SYNOPSIS
    Sets configuration entries.
 
.DESCRIPTION
    This function creates or changes configuration values.
 
    These can be used to provide dynamic configuration information outside the PowerShell variable system.
 
.PARAMETER Name
    Name of the configuration entry.
 
.PARAMETER Value
    The value to assign to the named configuration element.
 
.PARAMETER Handler
    A scriptblock that is executed when a value is being set.
 
    Is only executed if the validation was successful (assuming there was a validation, of course)
 
.PARAMETER Append
    Adds the value to the existing configuration instead of overwriting it
 
.PARAMETER Temporary
    The setting is not persisted outside the current session.
    By default, settings will be remembered across all powershell sessions.
 
.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.
     
.EXAMPLE
    Set-SPRConfig -Name Location -Value Online
 
    Sets the location to online (as opposed to onprem)
