Write a function countBottom() that takes a list as parameter, finds and returns the number of bottom values in the list.
A bottom value is less than its predecessor and its successor.
Assume that the list contains numbers.
Example: [4, 2, 3, 7, 6, 6, 4, 3, 5, 8, 6, 7, 5] has 3 bottoms, the first 2, the second 3, and last 6. All these values are less than their predecessor and their successor.
