CSHARP.STRUCT.EXCP.INAPP : Inappropriate Exception Handler (C#)

Summary

An exception class is caught that should be rather prevented.

This checker controls if exception handlers might be incorrect. For instance, an exception handler with an empty body might be an unfinished snippet of code; an exception handler for a very generic exception type might end up catching too many exceptions, also some that were not meant to be caught there.
