Misleading line comments

[ssackett]

Based on the names of the following two variables I think the line comments are wrong:
variable_cooling_tube_position
variable_cooling_tube_length

Example:
variable_cooling_tube_position should have the comment: Measured from Nozzle to Top of Heater Block
variable_cooling_tube_length should have the comment: Measured from Top of Heater Block to Top of Heatsink

I need to find a moment to carefully review the tip forming code/comments. That text was part of a PR and it "looked right" to me at the time.

From memory (not looking at the macro at the moment) are you sure that cooling_tube_position isn't the middle of the distance from top of heater to top of heatsink? (I need to double check the actual macro movement)
