option to provide template for resource listing
Fixed model inheritance bug #140
The `--api-doc-template` option will use the imported `swaggerVersion`, `apiVersion` and `basePath` as defaults.
Added resource filter example. 

Closes #141
Restructured Processors and Contexts

* Rewritten Context classes into one flexible Context class
* Decoupled Processors from the parser (Active Resource/Model is in the context)
* Context is a public property of Annotation, allowing access to parser meta data. closes #143
Compatibility with older PHP versions
Added context to DocParser error messages 

The position is converted back into line and character information.
Greatly improves debugging an error in a large docblock. #124
Additional validation + Swagger->inheritProperties() now utilizes the annotation->context
