Returns true if the current plugin matches passed name.
Remarks
Plugins can have multiple aliases, and comparing the names via strings is rather awkward - hence this function.
Example
.echo 'Output writer is ' #if outputwriteris('ti8x') .echo 'TI-83 Plus' #elseif outputwriteris('ti83') .echo 'TI-83' #else .echo 'not recognised' #endif .echoln '.'
