Converts a Lisp object to an appropriate jobject.
A jobject or
lisp-to-jobject tries to convert the argument lisp-object to a jobject. It succeeds if lisp-object is of a type that matches any Java primitive type or is a string. In general that means integers up to 64 bits, floats,
nil and strings.
See Types and conversion between Lisp and Java for a full description.
