Function to convert a decimal number to an array of Tris

[Espeer5]

We need a function which will convert any decimal number to an array of Tris the length of a word. This will need to do a few things:

• Check the decimal number to make sure it is within the bounds of what can be expressed in WORD_SIZE balanced Tris
• Compute each digit of the balanced ternary representation
• instantiate WORD_SIZE new Tri() objects and setState for each of them to the necessary value for the digit
• store these in an array and return them

The Tri object and methods are in tri.js The WORD_SIZE is found in constants.js

Note that balanced ternary means every digit can be either 0, 1, or -1. So for example (base 10 to balanced ternary):

• 2 --> "1-1"
• 3 --> "10"
• 4 --> "11"

Said function should be defined within conversions.js
