`DESCRIPTION`

- Implements a
*spigot*-algorithm; http://en.wikipedia.org/wiki/Spigot_algorithm. - Uses the traditional algorithm, rather than the
*unbounded*algorithm described by http://www.comlab.ox.ac.uk/jeremy.gibbons/publications/spigot.pdf.

openI :: Series I -> DecimalDigits -> IntegerSource

- Initialises a
*spigot*-table with the row of`coefficients`

. - Ensures that the row has suffient terms to accurately generate the required number of digits.
- Extracts only those digits which are guaranteed to be accurate.
- CAVEAT: the result is returned as an
`Integer`

, i.e. without any decimal point.
