#endif does not have #if ROOT dictionary

[anthoak13]

If you see the error along the lines of G__AtToolsLinkDef dictionary payload:1797:2: error: #endif without #if it likely means on of your header files does not end with a newline.

In that case ROOT shoves the headers together in a way where the #ifndef in the header guard is commented out by the previous header file.

An example of this can be seen in #243.

Look into adding a newline to each headfile we pass to rootcling in our CMake scripts
