Clojure Eval NAL-8 operator

[0xc1c4da]

We need a Clojure eval operator clj() that takes a product from NARS executes it and returns narsese statement of program output and/or errors.

Similar to the scheme() operator in NARS, however this operator has bugs with parsing and handling NARS variables.

eg.

clj(( (, +, 1, 2, ) ))

or

<"hello world" --> test>.
(&&, <#1 --> test>, clj(( (, println, #1, ) ))

triple parentheses for clj() function then product and then clojure parentheses as terms.
