Format Perl6 code.
Known limitations: if there is a BEGIN, there will not be any formatting. Also , if classes are imported from nqp.
Usage:
use Perl6::Format;
my $f= Perl6::Format.new(); # create a new object
say $f.format({indentsize=>4},$content); # format using indentsize 4.
Only identation size can be set now.
Command line access:
perl6 format.p6 -h
perl6 format.p6 -is 4 <Dagrammar.p6 >formatted.p6
