Similar to the {{#if:}}} parser function, this template checks if a page is in a category (first unnamed param), and outputs either the second or third unnamed parameter.
{{ifcategory|Lua-based templates|this template uses lua|this template does not use lua}}
gives this template uses lua since this page is in Category:Lua-based templates.
{{ifcategory|page=Stone|Blocks|stone is a block|stone is not a block}}
gives stone is a block since Stone is in Category:Blocks.
{{ifcategory|page=Nonexistent|noIfNonexistent=1|Blocks|this would have thrown an error|but it doesn't since <code>noIfNonexistent</code> is set}}
gives
but it doesn't since noIfNonexistent is set. This will suppress the error and output the third unnamed parameter.
