Detailed Description

A class for passing options to services.

It can be constructed from a Config, and in practice most options will be taken from site configuration, but they don't have to be. The options passed are copied and will not reflect subsequent updates to site configuration (assuming they're not objects).

Services that take this type as a parameter to their constructor should specify a list of the keys they expect to receive in an array. The convention is to make it a public const called CONSTRUCTOR_OPTIONS. In the constructor, they should call assertRequiredOptions() to make sure that they weren't passed too few or too many options. This way it's clear what each class depends on, and that it's getting passed the correct set of options. (This means there are no optional options. This makes sense for services, since they shouldn't be constructed by outside code.)
