function Send-TwitterOauth_AccessToken {
<#
.SYNOPSIS
    Authentication

.DESCRIPTION
    POST oauth/access_token
    
    Allows a Consumer application to exchange the OAuth Request Token for an OAuth Access Token. This method fulfills Section 6.3 of the OAuth 1.0 authentication flow.

.PARAMETER oauth_verifier
    If using the OAuth web-flow, set this parameter to the value of the oauth_verifier returned in the callback URL. If you are using out-of-band OAuth, set this value to the pin-code. For OAuth 1.0a compliance this parameter is required. OAuth 1.0a is strictly enforced and applications not using the oauth_verifier will fail to complete the OAuth flow.
