Display error when file or class name does not have first letter upper case

I would like to know if this would be a good error message to have some how for the next CI update.

That if a class or file name does not have first letter and only first letter upper case then should throw a error for the CI user even on a localhost

It will save people asking the same questions on forums like stackoverflow. why is my project working on localhost but not live server.

People are not reading the user guide.

There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
