Write a method that accepts two strings as input parameters then returns an "interlaced" combination of the two strings. What that means is that a character is taken from str1, then a character from str2. This continues until there are no more characters left in whichever string is shorter. Note that either string could be the shorter one. Also note that you may only use the following string methods: .length, .charAt, .substring, .equals, and .compareTo
