[python-control-discuss] fix to ctrlutil.unwrap

[Sawyer F. <mi...@ca...>]

hey, i've a quick fix to ctrlutil.unwrap to make it successfully unwrap
phase changes of greater than 4pi:

in this section:

    for k in range(len(angle)):
        # See if we need to account for angle wrapping
        if (angle[k] - last > period/2):
            wrap = -period
        elif (last - angle[k] > period/2):
            wrap = period

i've replaced setting the wrap value with incrementing it:

    for k in range(len(angle)):
        # See if we need to account for angle wrapping
        if (angle[k] - last > period/2):
            wrap -= period
        elif (last - angle[k] > period/2):
            wrap += period

also, what's the procedure for getting commit access to the repository?
