Lace is an access control engine written in Lua which implements a squid-like
 ACL system for Lua programs to use in controlling access to resources.
 .
 Lace provides a parser of rulesets and an engine to execute the parsed
 rulesets. It relies on the calling application to provide access
 control types and then Lace runs the boolean logic and returns an
 allow/deny result along with the location of the decision and any
 description provided by it.
