Provides the factory methods for constructing instances from various sources. The sources are parsed and string interpolations are resolved. A 'daisy-chain' cascade of successive configurations is possible. This is where the resultant set of keys is the set union of those in this configuration and those in the fallback's. For every overlapping key, the fallback's value is overridden by this configuration, which takes precedence.
When interpolating strings, all the keys known at the point of the interpolation are available, including those only defined in the fallback. This is done only once on each configuration, when it is loaded. Therefore, if a configuration is later used as a fallback for another, its interpolations do not get re-evaluated when the later configuration is loaded. This minor limitation allows considerable benefit in that the memory footprint and processing effort are both low; the converse of evaluating interpolations on the fly would be that processing effort would be higher, or about twice as much memory would be needed, or both.
