    The Validator object is used to check that supplied values 
    conform to a specification.
    
    The value can be supplied as a string - e.g. from a config file.
    In this case the check will also *convert* the value to
    the required type. This allows you to add validation
    as a transparent layer to access data stored as strings.
    The validation checks that the data is correct *and*
    converts it to the expected type.
    
    Some standard checks are provided for basic data types.
    Additional checks are easy to write. They can be
    provided when the ``Validator`` is instantiated or
    added afterwards.
    
    The standard functions work with the following basic data types :
    
    * integers
    * floats
    * booleans
    * strings
    * ip_addr
    
    plus lists of these datatypes
    
    Adding additional checks is done through coding simple functions.
    
    The full set of standard checks are : 
    
    * 'integer': matches integer values (including negative)
                 Takes optional 'min' and 'max' arguments : ::
    
                   integer()
                   integer(3, 9)  # any value from 3 to 9
                   integer(min=0) # any positive value
                   integer(max=9)
    
    * 'float': matches float values
               Has the same parameters as the integer check.
    
    * 'boolean': matches boolean values - ``True`` or ``False``
                 Acceptable string values for True are :
                   true, on, yes, 1
                 Acceptable string values for False are :
                   false, off, no, 0
    
                 Any other value raises an error.
    
    * 'ip_addr': matches an Internet Protocol address, v.4, represented
                 by a dotted-quad string, i.e. '1.2.3.4'.
    
    * 'string': matches any string.
                Takes optional keyword args 'min' and 'max'
                to specify min and max lengths of the string.
    
    * 'list': matches any list.
              Takes optional keyword args 'min', and 'max' to specify min and
              max sizes of the list. (Always returns a list.)
    
    * 'tuple': matches any tuple.
              Takes optional keyword args 'min', and 'max' to specify min and
              max sizes of the tuple. (Always returns a tuple.)
    
    * 'int_list': Matches a list of integers.
                  Takes the same arguments as list.
    
    * 'float_list': Matches a list of floats.
                    Takes the same arguments as list.
    
    * 'bool_list': Matches a list of boolean values.
                   Takes the same arguments as list.
    
    * 'ip_addr_list': Matches a list of IP addresses.
                     Takes the same arguments as list.
    
    * 'string_list': Matches a list of strings.
                     Takes the same arguments as list.
    
    * 'mixed_list': Matches a list with different types in 
                    specific positions. List size must match
                    the number of arguments.
    
                    Each position can be one of :
                    'integer', 'float', 'ip_addr', 'string', 'boolean'
    
                    So to specify a list with two strings followed
                    by two integers, you write the check as : ::
    
                      mixed_list('string', 'string', 'integer', 'integer')
    
    * 'pass': This check matches everything ! It never fails
              and the value is unchanged.
    
              It is also the default if no check is specified.
    
    * 'option': This check matches any from a list of options.
                You specify this check with : ::
    
                  option('option 1', 'option 2', 'option 3')
    
    You can supply a default value (returned if no value is supplied)
    using the default keyword argument.
    
    You specify a list argument for default using a list constructor syntax in
    the check : ::
    
        checkname(arg1, arg2, default=list('val 1', 'val 2', 'val 3'))
    
    A badly formatted set of arguments will raise a ``VdtParamError``.

    Validator is an object that allows you to register a set of 'checks'.
    These checks take input and test that it conforms to the check.
    
    This can also involve converting the value from a string into
    the correct datatype.
    
    The ``check`` method takes an input string which configures which
    check is to be used and applies that check to a supplied value.
    
    An example input string would be:
    'int_range(param1, param2)'
    
    You would then provide something like:
    
    >>> def int_range_check(value, min, max):
    ...     # turn min and max from strings to integers
    ...     min = int(min)
    ...     max = int(max)
    ...     # check that value is of the correct type.
    ...     # possible valid inputs are integers or strings
    ...     # that represent integers
    ...     if not isinstance(value, (int, long, basestring)):
    ...         raise VdtTypeError(value)
    ...     elif isinstance(value, basestring):
    ...         # if we are given a string
    ...         # attempt to convert to an integer
    ...         try:
    ...             value = int(value)
    ...         except ValueError:
    ...             raise VdtValueError(value)
    ...     # check the value is between our constraints
    ...     if not min <= value:
    ...          raise VdtValueTooSmallError(value)
    ...     if not value <= max:
    ...          raise VdtValueTooBigError(value)
    ...     return value
    
    >>> fdict = {'int_range': int_range_check}
    >>> vtr1 = Validator(fdict)
    >>> vtr1.check('int_range(20, 40)', '30')
    30
    >>> vtr1.check('int_range(20, 40)', '60')
    Traceback (most recent call last):
    VdtValueTooBigError: the value "60" is too big.
    
    New functions can be added with : ::
    
    >>> vtr2 = Validator()       
    >>> vtr2.functions['int_range'] = int_range_check
    
    Or by passing in a dictionary of functions when Validator 
    is instantiated.
    
    Your functions *can* use keyword arguments,
    but the first argument should always be 'value'.
    
    If the function doesn't take additional arguments,
    the parentheses are optional in the check.
    It can be written with either of : ::
    
        keyword = function_name
        keyword = function_name()
    
    The first program to utilise Validator() was Michael Foord's
    ConfigObj, an alternative to ConfigParser which supports lists and
    can validate a config file using a config schema.
    For more details on using Validator with ConfigObj see:
