    The interface with VMD. This code just provides a wrapper for the IMD interface functions, which allow to send
    particle positions to VMD. Additionally, VMD can send back a single integer value, called transfer_rate, which
    is accessible both from c and from Tcl. The IMD force feedback is not implemented.
