Quicksaving before first run on coldspringsharbor.

Added manipulations.c, which turns an array of bytes
into their hex representation.

Added a completely useless test suite.

Added manifesto.tex, which is, well, a dramatic name
for my notes to self and plan.

Added local.schema, which will be used by LDAP later on when
actually registering the photos in a database.
