Weaving Words2By2 - This is a new word game - Given two words of any length, write a program that will "weave" the words together. Take the two letters from String str1 and then two letters from String str2. Continue this pattern. If you have an odd length, concatenate a space on the end to make it even in length. Return the resulting "Weave Word". Example: "abc","ab" -> "ababc "
