<#
.SYNOPSIS
Starts a Pode Server with the supplied ScriptBlock.
 
.DESCRIPTION
Starts a Pode Server with the supplied ScriptBlock.
 
.PARAMETER ScriptBlock
The main logic for the Server.
 
.PARAMETER FilePath
A literal, or relative, path to a file containing a ScriptBlock for the Server's logic.
The directory of this file will be used as the Server's root path - unless a specific -RootPath is supplied.
 
.PARAMETER Interval
For 'Service' type Servers, will invoke the ScriptBlock every X seconds.
 
.PARAMETER Name
An optional name for the Server (intended for future ideas).
 
.PARAMETER Threads
The numbers of threads to use for Web, SMTP, and TCP servers.
 
.PARAMETER RootPath
An override for the Server's root path.
 
.PARAMETER Request
Intended for Serverless environments, this is Requests details that Pode can parse and use.
 
.PARAMETER ServerlessType
Optional, this is the serverless type, to define how Pode should run and deal with incoming Requests.
 
.PARAMETER StatusPageExceptions
An optional value of Show/Hide to control where Stacktraces are shown in the Status Pages.
If supplied this value will override the ShowExceptions setting in the server.psd1 file.
 
.PARAMETER ListenerType
An optional value to use a custom Socket Listener. The default is Pode's inbuilt listener.
There's the Pode.Kestrel module, so the value here should be "Kestrel" if using that.
 
.PARAMETER DisableTermination
Disables the ability to terminate the Server.
 
.PARAMETER Quiet
Disables any output from the Server.
 
.PARAMETER Browse
Open the web Server's default endpoint in your default browser.
 
.PARAMETER CurrentPath
Sets the Server's root path to be the current working path - for -FilePath only.
 
.PARAMETER EnablePool
Tells Pode to configure certain RunspacePools when they're being used adhoc, such as Timers or Schedules.
 
.EXAMPLE
Start-PodeServer { /* logic */ }
 
.EXAMPLE
Start-PodeServer -Interval 10 { /* logic */ }
 
.EXAMPLE
Start-PodeServer -Request $LambdaInput -ServerlessType AwsLambda { /* logic */ }
