Noteworthy

• Dagger2 depends on code generation, and annotation processing must be enabled in bld build class.
• Do not reuse regular source directory for generated classes. Instead, define in build class a custom generated source folder and add it in your IDE.
• One key aspect when dealing with compile-time solutions like Dagger is how erros tend to be more present at compile-time than runtime. Reflection-heavy applications tends to show errors at runtime only.
• Due to some IDE misconfiguration, annotation processing isn't regenerating the classes into the directory defined in bld build. Whenever change something in the Module or in the Component, first delete the packages under the generated folder, then recompile it with ./bld compile to get a sane classpath again.
