Description: Description This implements software_columns() as a new feature to help in the tricky task of printing texts in columns or aligning multiple texts in different alignments within the same line. The method receives a list of strings and formats them as horizontal columns by adding spaces between each element. If some text is too long it is wrapped to the column width by adding new lines and even truncating words that are too long by adding a placeholder. It is also possible to set the width and the text alignment of each column independently. The method is flexible enough to repeat the last width and/or alignment till the last element if there are more text elements than column widths or alignments. Example 1: The user passes a list of 4 text items and wants the first one to be 20 characters wide and 10 for the rest, then he/she only needs to pass the value widths=[20, 10] to the method so it will be expanded to '[20, 10, 10, 10]`. Example 2: The user passes a list of 4 text items and wants all them to be the same size along a maximum total width of 40 characters, then he/she simply passes the value widths=40 so it will be expanded to [10, 10, 10, 10]. This is also true for the alignment parameter: On a list of 4 text items align=['left', 'center', 'right'] would expand to ['left', 'center', 'right', 'right']. Alternatively a single value align='center' would expand to ['center', 'center', 'center', 'center']. At the moment, the user is responsible for not exceeding the width of the paper when passing the list of widths parameter, but this behavior could be modified by adding a check, an exception or whatever. As always all suggestions, corrections, etc. are very welcome. Closes #27 Closes #635 Tested with Epson TM-U210
