Compute the probability of heads with each flip given a linear change model.

prob_heads_linear(nflips, preflip_prob = 0.5, slope = 0.1)

## Arguments

nflips Total number of flips (heads and tails) Probability of heads before the coin is handled How much the probability changes each time the coin is flipped

## Value

Vector of probability of heads for the first flip, second flip, etc.
