How can I create my own custom tech tree?

[sojourner-fishsticcc]

hi!

currently trying to develop my own overhaul mod for ksp and am hoping to give it an rp-1 style custom tech tree that can tag what parts it wants to be in what nodes without needing to modify the part files themselves.  and beyond that, i have no idea where to start with making a tech tree and can't find any threads here about that. basically:

 - how can i create my own tech tree?

 - how can i make the nodes specify the parts they should contain instead of making the parts specify what node they belong in?

 - how can i give the tech nodes custom images beyond the ones the game already has?

along with this, how can i make this have compatibility with b9-partswitch variants of parts so they can only be unlocked once their parent node is unlocked. i'm hoping to have the nodes also affect things like the effectiveness of all solar panels.
