  "message": "Extend the C API to support loss functions\n\nThis extends the C API to support loss functions. Both\nuser-supplied cost functions as well as the stock Ceres cost\nfunctions (Cauchy, Huber, etc) are supported. In addition, this\nadds a simple unit test for the C API.\n\nSupporting loss functions required changing the signature of the\nceres_add_residual_block() function to also take a thunk for the\nloss function.\n\nChange-Id: Iefa58cf709adbb8f24588e5eb6aed9aef46b6d73\n",
