/**
* Request for the history of a piece of configuration.
* <p>
* A full configuration master implements historical storage of data.
* History can be stored in two dimensions and this request provides searching.
* <p>
* The first historic dimension is the classic series of versions.
* Each new version is stored in such a manor that previous versions can be accessed.
* <p>
* The second historic dimension is corrections.
* A correction occurs when it is realized that the original data stored was incorrect.
* A simple configuration master might simply replace the original version with the corrected value.
* A full implementation will store the correction in such a manner that it is still possible
* to obtain the value before the correction was made.
* <p>
* For example, a piece of configuration added on Monday and updated on Thursday has two versions.
* If it is realized on Friday that the version stored on Monday was incorrect, then a
* correction may be applied. There are now two versions, the first of which has one correction.
* This may continue, with multiple corrections allowed for each version.
* <p>
* Versions and corrections are represented by instants in the search.
*
* @param <T> the configuration element type
