    """Fixe arguments from a script tool.

    For example, when using a script tool with a multivalue parameter,
    it comes in as "val_a;val_b;val_c".  This function can automatically
    fix arguments based on the arg_type.
    Another example is the boolean type returned from a script tool -
    instead of True and False, it is returned as "true" and "false".

    Required:
    arg --  argument from script tool (arcpy.GetParameterAsText() or sys.argv[1]) (str)
    arg_type -- type to convert argument from script tool parameter. Default is list.

    Example:
    >>> # example of list returned from script tool multiparameter argument
    >>> arg = "val_a;val_b;val_c"
    >>> fixArgs(arg, list)
    ['val_a', 'val_b', 'val_c']
