Nidoran DV Formula

Expands on http://pastebin.com/GgZQ9vxu

let x = atkDV * 16 + dfnDV
let y = spdDV * 16 + spcDV

//Then for grass with encounter rate 25 (i.e. Nidorans):
floor(13 + 3/2 * y) <= x <= floor(26 + 3/2 * y)
or
floor(141 + 3/2 * y) <= x <= floor(154 + 3/2 * y)

//Extra comparisons to complete possibilities
or
floor(13 + 3/2 * y) <= x+256 <= floor(26 + 3/2 * y)
or
floor(141 + 3/2 * y) <= x+256 <= floor(154 + 3/2 * y)
or
floor(141 + 3/2 * y) <= x+512 <= floor(154 + 3/2 * y)
