The main idea behind FIRST is to preserve an engineer's analysis
of certain functions (name, prototype, comment, etc) by using methods
like opcode hashing, mnemonic hashing, locality sensitive hashing,
etc. By collecting and storing these signatures centrally the
framework can provide them later to the community via the API/Plugin.
The goal is to provide quick lookups for similar functions to avoid
losing time with analysing a function which was already analysed
before in another sample or by another engineer.
