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.
Now accepts argument '-f', for which the argument is a file path.
Opens file, then reads input from it.
If file is not provided or fopen() fails, ldaphotos defaults to reading message from standard input.
