Exercise 02 - repeatString

Write a function that simply repeats the string a given number of times:

repeatString('hey', 3) // returns 'heyheyhey'

You will notice in this exercise that there are multiple tests (see in file repeatString.spec.js). Only the first test is currently enabled. So after making sure that this first one passes, enable the others one by one by deleting the x in front of the it() function.

Hints

You're going to want to use a loop for this one.
Create a variable to hold the string you're going to return, create a loop that repeats the given number of times and add the given string to the result on each loop.
If running jasmine repeatString.spec.js raises Temporarily disabled with xit errors, make sure you have enabled the rest of the tests (see above).
