   CREATED BY: Vadim Melamed, EMAIL: vmelamed5@gmail.com
.DESCRIPTION
   USE THIS FUNCTION TO ADD ALLOWED REFERRERS TO CYBERARK
.PARAMETER NoSSL
   If the environment is not set up for SSL, API calls will be made via HTTP not HTTPS (Not Recommended!)
.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 ReferrerURL
   Target URL that will be whitelisted to allow the PVWA to redirect from
.PARAMETER RegularExpression
   Define if the ReferrerURL will be treated as a regular expression
.EXAMPLE
   $AddAllowedReferrerStatus = Add-VPASAllowedReferrer -ReferrerURL {REFERRERURL VALUE} -RegularExpression
.OUTPUTS
   $true if successful
   $false if failed
