Comment 1 for bug 1343678

1. Have to create a library before creating procedure and should point to jar file, not class file.
To do: document the correct process in README

2. Create procedure statement has to specify library name and remove external path. Also, the example SPJ does not have SQL, so no need for CONTAINS SQL clause.
To do: Library is required. Remove CONTAINS SQL

3. Should not print cstmt, its printing some internal statement handle id.
To do: comment the log

4. README needs to be fixed: the class file should be put in a jar file. And the jar file has to be copied to all nodes in a cluster.
To do: document this comments in README
