An instance of this class represents a plain sidereal time in the range [0,24) hours. No attempt is made inside the object to record whether it represents Greenwich sidereal time (GST) or local sidereal time (LST).
Although the constructor accepts a value in hours, internally the value is stored as radians normalized to the interval [0,2π).

class SiderealTime:
"""Represents a sidereal time value.
State/Internals:
.hours: [ self as 15-degree hours ]
.radians: [ self as radians ]
"""
The time in hours is first normalized to the interval
[0,24) and stored in self.hours, then
converted to radians and stored in self.radians.
