lazy static regexes checked at compile time - Rust source code

 Lazy-regex enables you to use the `regex!` macro to build regexes:
  * they're checked at compile time
  * they're wrapped in `once_cell` lazy static initializers
    so that they're compiled only once
  * they can hold flags as suffix:
    `let case_insensitive_regex = regex!("ab*"i);`
  * regex creation is less verbose
 .
 This macro returns references to normal instances of `regex::Regex`
 so all the usual features are available.
 .
 This package contains the source for the Rust lazy-regex crate,
 packaged for use with cargo and dh-cargo.
