Thanks, well that's better.
I was going by ZF2 Module Structure (
http://framework.zend.com/manual/2.2/en/modules/zend.mvc.intro.html.)
Right now, other developers will hate me for having to refer to my class like this:
"./module/Device/src/Device/Entity/Device.php"
because this entire 5-level-deep directory structure is set up for one class (at the moment). Even when I have 10 classes there, the depths will remain the same.
I could instead do something like "./module/Device/src/Device/Device.php" to aid separation without too much depths, or even "./module/Device/Device/Device.php", but that's moving away from ZF2 structure and I want to go towards it.
