Feature: printf()

The function printf() in Rhost can be used to greatly reduce coding in efforts for outputs, screens and data display. It can automatically center, justify and wrap the text parameters given to it.

Consider the following examples:

> @emit printf(|$-12s|$12s|$^12s$&14s$_12s|,a b c, d e f, g h i, wrap(lnum(20),12, l, |, |), j k l)

|a b c       |       d e f|   g h i    |0 1 2 3 4 5 |j     k    l|
                                       |6 7 8 9 10  |
                                       |11 12 13 14 |
                                       |15 16 17 18 |
                                       |19          |
