Documentation

The Interval class represents time intervals. This class complements and is compatible with the Time class which represents absolute GPS times. At present, intervals are represented as double-precision floating point numbers. This gives about 53-bits to the representation which corresponds to a precision of 1 in or <1ns for intervals of up to ~100 days.
