/*@C
     PetscBoxUpload - Loads a file to the Box Drive

     This routine has not yet been written; it is just copied from Google Drive

     Not collective, only the first process in the MPI_Comm uploads the file

  Input Parameters:
+   comm - MPI communicator
.   access_token - obtained with PetscBoxRefresh(), pass NULL to have PETSc generate one
-   filename - file to upload; if you upload multiple times it will have different names each time on Box Drive

  Options Database:
.  -box_refresh_token   XXX

  Usage Patterns:
    With PETSc option -box_refresh_token  XXX given
    PetscBoxUpload(comm,NULL,filename);        will upload file with no user interaction

    Without PETSc option -box_refresh_token XXX given
    PetscBoxUpload(comm,NULL,filename);        for first use will prompt user to authorize access to Box Drive with their processor

    With PETSc option -box_refresh_token  XXX given
    PetscBoxRefresh(comm,NULL,access_token,sizeof(access_token));
    PetscBoxUpload(comm,access_token,filename);

    With refresh token entered in some way by the user
    PetscBoxRefresh(comm,refresh_token,access_token,sizeof(access_token));
    PetscBoxUpload(comm,access_token,filename);

    PetscBoxAuthorize(comm,access_token,refresh_token,sizeof(access_token));
