cargo apply

A Coccinelle-based approach to applying modifications to a cargo workspace.

Scope of possible manipulations may also encompass TOML files changes and build.rs edits.

Tiniest scope is to be able to:

• find crates that use a given lib's version
• try any crate with a pass of the semantic code patch being developped
