I'm interested in using CAMB. Can you tell me what programming languages it's written in, two key features related to its accuracy and speed, and how I can access its Python documentation?
Navigate to 'camb.info'. Identify the programming languages CAMB is written in from the 'Features' section. Locate and extract two key features related to CAMB's accuracy and speed from the 'Features' section. Find the link or instructions for accessing the Python documentation. Synthesize all collected information into a concise answer.
State that CAMB is written in 'Python and Fortran'. Identify and state 'Fast computation to ~0.1% accuracy, with controllable accuracy level' as one key feature. Identify and state 'Optimized Python and Fortran code' as another key feature related to speed/optimization. State that the Python documentation can be accessed via a link directly from the main page, or by mentioning 'Python documentation' is listed under 'Download the source code and see'.
