        FilterExpression

Parses a variable token and its optional filters (all as a single string), and return a list of tuples of the filter name and arguments. Sample:

>>> token = 'variable|default:"Default value"|date:"Y-m-d"'
>>> p = Parser('')
>>> fe = FilterExpression(token, p)
>>> len(fe.filters)
2
>>> fe.var
'variable'

This class should never be instantiated outside of the get_filters_from_token helper function.
