improve length$ function

forgot to add rad-neq to the function group

fixed bug with rad-equals

adding method to make it easier to execute functions from java programs

updated jar with radix func

adding radix functions

finally found the bug with the not equals conditional element when there are multiple, silly logic error. didn't catch this since manners benchmark only has 1 rule that uses notEquals and it only uses 1 slot.

I'm stupid, the engine was correct, the rule I wrote to test joins with 2 not equal slots was matching too eagerly since the facts were in both sides duh!
