Module Tezos_raw_protocol_015_PtLimaPt.Script_interpreterSource
This is the Michelson interpreter.
This module offers a way to execute either a Michelson script or a Michelson instruction.
Implementation details are documented in the .ml file.

Tezos_protocol_environment_015_PtLimaPt.Lwt.texecute ?logger ctxt ~cached_script mode step_constant ~script ~entrypoint ~parameter ~internal interprets the script's entrypoint for a given parameter.
This will update the local storage of the contract step_constants.self. Other pieces of contextual information (source, payer, amount, and chaind_id) are also passed in step_constant.
internal is true if and only if the execution happens within an internal operation.
mode is the unparsing mode, as declared by Script_ir_translator.
cached_script is the cached elaboration of script, that is the well typed abstract syntax tree produced by the type elaboration of script during a previous execution and stored in the in-memory cache.

Internal interpretation loop ============================
The following types and the following functions are exposed in the interface to allow the inference of a gas model in snoop.
Strictly speaking, they should not be considered as part of the interface since they expose implementation details that may change in the future.
