/**
  @file mv_getusergroups.sas
  @brief Creates a dataset with a list of groups for a particular user
  @details If using outside of Viya SPRE, then an access token is needed.

  Compile the macros here:

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

  Then run the macro!

      %mv_getusergroups(&sysuserid,outds=users)

  @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
