Warning - Work in Progress

This crate is based on VSS (Virtual String System). VSS has been split into two crates:

• vss_text: a library for Unicode text processing.
• vss_extra (this crate): libraries for handling JSON, Regexp, XML and other features based on vss_text.

Significant API changes are planned in vss_text which will likely have an impact on this crate.

Moreover, vss_extra is planned to be further split into more focused projects (e.g. JSON, Regexp, XML, etc.) and might ultimately disappear once all features find a new home.
