                                Function Remove-SupplementalSigners {

    <#

.SYNOPSIS

    Removes the entire SupplementalPolicySigners block

    and any Signer in Signers node that have the same ID as the SignerIds of the SupplementalPolicySigner(s) in <SupplementalPolicySigners>...</SupplementalPolicySigners> node

    from a CI policy XML file

.NOTES

    It doesn't do anything if the input policy file has no SupplementalPolicySigners block.

    It will also always check if the Signers node is not empty, like

   <Signers>

   </Signers>

   if it is then it will close it: <Signers />

   The function can run infinite number of times on the same file.
