Typo in name of error @Output

[jrista]

It looks like the name of the error @output is actually typoed as errror, with three Rs in a row. In the handleError function, it is trying to reference this.error.emit, and throws because error does not exist.

I have put together a dynamic documentation system where there is the potential for a markdown file to not exist. I need to be able to handle those errors, so a quick fix for this would be great.

Thanks!
