Template:R from high-use template/doc

Usage
This is a version of high-use in rcat form. It should only be used for template redirects with a very high number of transclusions. While there is no exact guideline for this, this isn't generally necessary on templates with <5,000 transclusions, as templates with 5,000 transclusions are given template protection which is easily noticeable. Template redirects with >100,000 transclusions should be tagged.
