Deprecation of Triton-C and Replacement by decorated Python functions (#86)

Browse Source 
This PR implements a major overhaul of the frontend for Triton, and replaces Triton-C by a pure Python API in which kernels are defined as @triton.jit decorated functions. The documentation and tutorials have also been updated to accommodate these changes.

See documentations for more information on the new API
