/**
  @file mv_getclients.sas
  @brief Get a list of Viya Clients
  @details First, be sure you have an access token (which requires an app token).

  Using the macros here:

      filename mc url
        "https://raw.githubusercontent.com/sasjs/core/main/all.sas";
      %inc mc;

  An administrator needs to set you up with an access code:

      %mv_registerclient(outds=client)

  Navigate to the url from the log (opting in to the groups) and paste the
  access code below:

      %mv_tokenauth(inds=client,code=wKDZYTEPK6)

  Now we can run the macro!

      %mv_getclients()

  @param access_token_var= The global macro variable to contain the access token
  @param grant_type= valid values are "password" or "authorization_code" (unquoted).
    The default is authorization_code.
  @param outds= The library.dataset to be created that contains the list of groups
