Merge pull request #185 from vladimir-v-diaz/develop

Remove find-code.sh
Note: We are replacing find-code.sh because git-grep does the same, and more. Also, a development script unrelated to TUF should probably not be included in the source. Developers who may modify the source are likely to have their preferred way of doing things.
