fix(writer): fix makeDir directory tree bug
[Broken]: minErr doc generator

Should generate doc files from the format:

@ngdoc error
@name Injector: Unknown Provider
@code $injector: unpr
@description
...

It is currently failing. When run over several ngdoc files, only one
will get compiled. I'm still trying to figure out what went wrong.
[Less broken]: UI sucks but error messages viewable
