trying some stuff out with world_gen.
i've got some better ideas...
^ gen_world() + gen_landscape() Generating landscapes! With programmable slopes!

I can generate a landscape with a variable slope! hooray!
add pictures
added option to visualize the building of the terrain and added graphics.h to put graphics functions in like print_cells() and draw_line()
I made a line drawing tool. now I can use this to display my lines for when i'm generating my world  :D
I have not done the above yet. that still needs to be implemented. but the hard part is over.

fixed draw_line() and made a great visualization for gen_world().
now you can see with retro style neon-green lines how the world is generated
