Summary: Common Query Language Parser
Description: 
CQL::Parser provides a mechanism to parse Common Query Language (CQL)
statements. The best description of CQL comes from the CQL homepage
at the Library of Congress <http://www.loc.gov/z3950/agency/zing/cql/>

CQL is a formal language for representing queries to information
retrieval systems such as web indexes, bibliographic catalogs and museum
collection information. The CQL design objective is that queries be
human readable and human writable, and that the language be intuitive
while maintaining the expressiveness of more complex languages.

A CQL statement can be as simple as a single keyword, or as complicated as a set
of compoenents indicating search indexes, relations, relational modifiers,
proximity clauses and boolean logic. CQL::Parser will parse CQL statements
and return the root node for a tree of nodes which describes the CQL statement.
This data structure can then be used by a client application to analyze the
statement, and possibly turn it into a query for a local repository.

Each CQL component in the tree inherits from CQL::Node and can be one
of the following: CQL::AndNode, CQL::NotNode, CQL::OrNode,
CQL::ProxNode, CQL::TermNode, CQL::PrefixNode. See the
documentation for those modules for their respective APIs.
