A simple Corona SDK module. Includes a function that adjusts the spacing between the words on each line of the given text so that the left and right margins are the same. The function returns a display group with a top-left anchor point.
Example output:
#Syntax

This function takes a single argument, options, which is a table that accepts the following parameters:

#Gotchas
(1) You can't change the anchor point of the returned display group. It's fixed at 0, 0.
(2) The justified text can't be modified. If you need to modify a word within the text the whole paragraph must be recreated.
