/**
* A class for recording the definition of Mink replacements for use in Mink selectors.
*
* These are comprised of a source string, and a replacement.
*
* During use the source string is converted from the string to be in the format:
*
* %[component]/[string]%
*
* For example:
*
* %mod_forum/title%
*
* Mink replacements are used in xpath translation to translate regularly used items such as title.
* Here is an example from the upstream Mink project:
*
* '%tagTextMatch%' => 'contains(normalize-space(string(.)), %locator%)'
*
* And can be used in an xpath:
*
* .//label[%tagTextMatch%]
*
* This would be expanded to:
*
* .//label[contains(normalize-space(string(.)), %locator%)]
*
* Replacements can also be used in other replacements, as long as that replacement is defined later.
*
* '%linkMatch%' => '(%idMatch% or %tagTextMatch% or %titleMatch% or %relMatch%)'
