 This file defines a macro that returns the current date during the build (compilation) of the project.
 \n The macro is __INT_DATE__ and returns a 32-bit integer in the format YYYYMMDD (decimal).
 \n Use the variable #FW_version, to be defined in the main as a global.
 \n N.B.: the project must be rebuilt completely (not just F7) in order to update the macro.
 \n The macro is developed around the pre-processor __DATE__ that expands to current date (at compile time) 
 in the form mmm dd yyyy (e.g. "Jan 14 2012"), 
 as a string. The __DATE__ macro can be used to provide information about the particular moment a binary was built.
