   DELETE APPLICATION ID
   CREATED BY: Vadim Melamed, EMAIL: vmelamed5@gmail.com
.DESCRIPTION
   THIS FUNCTION DELETES AN APPLICATION ID FROM CYBERARK
.PARAMETER token
   HashTable of data containing various pieces of login information (PVWA, LoginToken, HeaderType, etc).
   If -token is not passed, function will use last known hashtable generated by New-VPASToken
.PARAMETER AppID
   Unique ApplicationID (or Application Name) that will be used by the credential provider(s) to retrieve credentials
.PARAMETER WhatIf
   Run code simulation to see what is affected by running the command as well as any possible implications
   This is a code simulation flag, meaning the command will NOT actually run
.PARAMETER HideWhatIfOutput
   Suppress any code simulation output from the console
.EXAMPLE
   $WhatIfSimulation = Remove-VPASApplication -AppID {APPLICATION ID VALUE} -WhatIf
.EXAMPLE
   $DeleteApplicationStatus = Remove-VPASApplication -AppID {APPLICATION ID VALUE}
.OUTPUTS
   $true if successful
   $false if failed
