If a geometry data use this ex.
[1 1 1 1 1 1] [4 4 4 4 4 4]
[ 123 123 123
123 123 123
[ -1 1 1
1 1 -1
1 1 1 ]
So what I'm look for is how to pick up a begin character
and end character so I could extrate the 4 array
say my $begin1 = '['
and my $end1 = ']'
build a array between begin and end
I have test with simple qw but I like to
search and match a begin and end character to.
I could give more example but the script would pick
up 'renderman rib' file and pick the data between 
and build a new data from that.
