* the .ino.cpp file includes all include directives and definitions in all the ino and pde files

* it also includes a include statement for all the ino and pde files themelves

* This way compiling the ino.cpp file compiles all ino and pde files in 1 file with declarations on top just like arduino ide does

*

* the custom managed build system delivered with the plugin ignores the ino and pde files

* this way the ino and pde files are only build once

*

* because I do not touch the ino and pde files the references returned by the toolchain

* are still perfectly valid removing the need for post processing

*

* Arduino ide ignores files starting with a . making the solution 100% compatible between arduino IDE and eclipse

*

* in standard configuration eclipse does not show the .ino.cpp file in the project explorer making the solution nice and clean from a visual perspective.

*

* I'm currently aware of 1 drawbacks of this solution

* If you have a file called .ino.cpp already in your project that file will be overwritten.
