Modified files (4): PyArray, PySequence, jarray,
test_jarray
New files (1): org.python.core.ArrayHelper

First cut at cpython 2.2 implementation.  Many new
features 
implemented including:
typecode, append, count, extend, index, insert, pop,
remove, reverse

Still outstanding:
itemsize, buffer_info, byteswap, fromfile, fromlist,
fromstring,
tofile, tolist, tostring
(somewhich may not make sense in jython).

test_jarray is now a merged version of the cpython2.2
test and 
the jython 2.1 test with features not yet implemented 
commented out.

Please check your unit tests before and after to make sure
I didn't break anything (I didn't have a baseline to
compare to).
