Issue description

Hi I wanted to know if there was any way to make a procedure happen in a range, as in you give it the start co-ordinate (e.g. x:x-10 y:y+12 z:z) and the end     co-ordinate (e.g. x:x+10 y:y-12 z:z) and make for example lightning to strike all blocks in that area?

Thank you in advance :)
