###About
Cinder block, that has no dependancies, for simple SHA1 hashing.
###Todo
- add exception throwing on any errors (especially when trying to checksum non existing file)
Cinder comes with Boost which has boost::uuids::detail::sha1 in boost/uuid/sha1.hpp and of course it works, but we find this small helper class more attractive for quick checksumming files downloaded from interwebs.
###Example
fs::path pathToFile = getAssetPath("file.ext");
SHA1 mySha1;
string checkSum;
checkSum = mySha1.from_file( pathToFile.string() );
cinder::app::console() << "file checksum: " << checkSum << endl;
