com.android.tools.lint.detector.api.Context
Context passed to the detectors during an analysis run. It provides information about the file being analyzed, it allows shared properties (so the detectors can share results), it contains the current location in the document, etc.
TODO: This needs some cleanup. Perhaps we should split up into a FileContext and a ProjectContext.
NOTE: This is not a public or final API; if you rely on this be prepared to adjust your code for the next tools release.
