It collects the total Lines Of Code(loc), the None Comment Lines Of
Code(ncloc), the Comment Lines Of Code(cloc) and a approximated
Executable Lines Of Code(eloc) for files, classes, interfaces,
methods, properties and function.
The current implementation has a limitation, that affects inline comments.
The following code will suppress one line of code.
function foo() {
foobar(); // Bad behaviour...
}
The same rule applies to class methods. mapi, PLEASE, FIX THIS ISSUE.
