Ninety-Nine Scala Problems: Problem 10 - Run-length encoding of a list.

	// http://aperiodic.net/phil/scala/s-99/

	// P10 (*) Run-length encoding of a list.
	// Use the result of problem P09 to implement the so-called run-length encoding data compression method. Consecutive duplicates of elements are encoded as tuples (N, E) where N is the number of duplicates of the element E.
	// Example:

	// scala> encode(List('a, 'a, 'a, 'a, 'b, 'c, 'c, 'a, 'a, 'd, 'e, 'e, 'e, 'e))
	// res0: List[(Int, Symbol)] = List((4,'a), (1,'b), (2,'c), (2,'a), (1,'d), (4,'e))

Project Euler - Problem 02 - Find the sum of the even-valued terms.

	// http://projecteuler.net/problem=2

	// Each new term in the Fibonacci sequence is generated by adding the previous two terms.
	// By starting with 1 and 2, the first 10 terms will be:

	// 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

	// By considering the terms in the Fibonacci sequence whose values do not exceed four million,
	// find the sum of the even-valued terms.
