Sees if you have a flush, and if so, how high it is.

1	flush1(x, y)

`x`	vector of numbers of your cards and the board cards, together.
`y`	corresponding suits of your cards and the board cards.

Can break down if dealing with 10 cards or more, i.e. if 2 flushes are possible

returns 0 if you don't have a flush, or 15^4 times top number + 15^3 times 2nd-highest + ... if you do.

Frederic Paik Schoenberg

x = c(2,14,8,8,5,3,4)
y = c(1,2,4,1,1,1,1)
flush1(x,y)
x = c(2,14,8,8,5,3,4)
y = c(1,2,4,1,3,1,1)
flush1(x,y)
