In PirateGrunt/OriginPeriod: Organizes time periods

OriginPeriod is an S4 class used to store information about the time intervals which produces claims, exposure or some other measure. This is a utility class, primarily of interest to actuaries.

Several things distinguish an OriginPeriod from other date/time vectors.

1. A starting and ending date are both required. 2. The time period between the starting and ending date must be constant. 3. The start and end dates must be monotonically increasing 4. The user may apply a label to each period 4. The time periods may not overlap (?)

An OriginPeriod may be of any arbitrary length, though years are most common. The "type" slot is a character string which indicates the type of origin period, such as "Accident", "Occurrence", "Report", "Policy", "Lloyds" and so forth. "Accident" and "Occurrence" are synonymous and indicate the a claim occurred in a particular period of time. "Report" is the interval during which a claim is reported, such as exists under a claims-made policy. "Policy" or "Underwriting" periods are ones wherein the risk attaches. "Lloyds" refers to a Lloyds year of account. There is no restriction on what type may be used for an OriginPeriod, meaning that there is no language restriction either. So, "Zeichnungsjahr", "Ereignisjahr" and so forth are permitted.
