added type tests

As a result these changes were made:
- Simplified a few New* functions
- Allowed empty inclusion and consistency proofs, which is in contrast
to not being able to marshal them due to `tls:"minlen:1"`.  For example,
an inclusion proof will be empty for a Merkle tree of size 1.
- Disallowed empty signatures and chains in a leaf's Appendix
- Removed unnecessary examples
