Issue 173 coordinate system integration

[ChristopherCampos]

-Integrated Manual mode which allows for coordinate placing capabilities -Calculates needed cable capacity and length for each segment through an array system. -Accounts for terminal cable length -Changed variable names to stay consistent -Added user defined homerun trench flag

Hi! I would like to know how accurate cables are selected, is it just a matter of power rating of the cable? or does it calculate the current reductions due to restricted heat dissipation, voltage drop and short circuit current?

Thank you so much for your work. It is really appreciated :)
