> Given that Addons A(1.0), B (1.0), C(1.0)  are installed in an AddonRepository, and C(1.0) depends on B(1.0), when an addon D(1.0) to be installed requires B(1.1), there should be a way to warn against incompatibilities and let the user decide what to do. Same when D(1.0) depends on B(2.0)
> Basically an addon version is composed of Major.Minor.Micro
> In relation to the installed addon version and the requested addon version the following rules should be followed: 
> - When Major version is different, the addons are assumed be completely incompatible (even if in practice that is not true). Fail installation
> - When Minor version is different, compatibility may be assured only if the requested version is less or equal to the required version. Prompt for installation of necessary version.
> - When Micro version is different, the addon is totally compatible, thus no  compatibility check is required. No problem to install
