Function syntax for native java objects

I'm making some good progress on integrating java objects.

I now have function syntax working for object variables.

Here's an interesting example of mixing functions, jset, and the function syntax

# Define a function jnew which creates a String

$ jnew () {

local _x ;

jset -v _x -c java.lang.String "$@"

return $_x;

}

# Create a string object

$ a=jnew("hi there")

# Check its value

$ echo $a

hi there

# Check its type

$ xtype $a

java.lang.String

# Call the length method

$ echo a.length()

8

# Call the concat method

$ echo a.concat(" some more")

hi there some more
