nj22 in NetBeans

[John Caron]

nj22 is not optimized for high performance, or really for writing, so i would be interested in what you can acheive.

make sure you put time as the unlimited dimension, make sure fill values are off, is the only advice i can think of. if i get a chance i will try a test case.
