//! Generic code to parse a period -- no matter the period type.

     *  the elements will be instances of a date which will be parsed
     *  according the to setup in the passed facet parameter.
     *
     *  The steps for parsing a period are always the same:
     *  - consume the start delimiter
     *  - get start element
     *  - consume the separator
     *  - get either last or end element depending on range settings
     *  - consume the end delimeter depending on range settings
     *
     *  Thus for a typical date period the contents of the input stream
     *  might look like this:

     *

     *    [March 01, 2004/June 08, 2004)   <-- open range
