Create a Node.js program that:

  * Asks the user for the number of times to flip a coin
  * Asks the user for the probability the coin lands heads side up as a decimal
    (0.5 would mean there is a 50% chance that the coin lands heads up). 
  * Flips the coin the specified number of times, tracking the number of times
    the coin lands on heads or tails.
  * Prints out the number of times the coin landed heads up and tails up.

HINT: If you can generate a random number in the range [0.0 - 1.0) [inclusive,
exclusive), then you can simulate an event occurring with a probability, p,
using:

```js
if (random_number < p) {
  // the event happened
} else {
  // the event did not happen
}
```
