Title: Adding operation number to create a unique href for the <a/> tag.

In some cases, identifying an operation with resource name, nickname and HTTP Method is not enough. An extra identifier should be added to differentiate among same operations but with differente parameters. So in order to do that, a new field was introduced: `number`. This makes each operation unique even if they differ by the arguments.
