+/**
+ * ContextQuery allows to search for context that match a pattern.
+ *
+ * Query Syntax and Semantics
+ *
+ *        query = [ "/" ], { part, "/" }, part ;
+ *        part = string | "*" | "**" | properties ;
+ *        properties = property, { ",", property } ;
+ *        property = string, "=", value ;
+ *        value = string | number | boolean ;
+ *        string = quoted string | symbol ;
+ *        quoted string = '"', {any-character - ('"' | '\') | ('\', ('"' | '\'))}, '"' ;
+ *        symbol = letter, { letter | digit } ;
+ *        number = digit, { digit } ;
+ *        boolean = "true" | "false" ;
+ *        letter = ? A-Z, a-z or _ ? ;
+ *        digit = ? 0-9 ? ;
+ *        any-character = ? any character ? ;
+ *
+ * To give a feel for the syntax, here are some examples, and what a user
+ * might mean when providing such a query:
+ *
+ * httpd
+ *        Matches all contexts named "httpd".
+ *
+ * pid=4711
+ *        Matches any context with a property pid, which has the value 4711.
+ *
+ * /server/**
+ *        Matches all contexts which are decendants of the top level context
+ *        named "server".
+ *
+ * "Linux 2.6.14"/Kernel/*
+ *       Matches all kernel processes in operating systems named "Linux 2.6.14".
+ *
+ * pid=4711/*
+ *        All threads in processes with the pid 4711.
+ *
+ * /server/** /HasState=true
+ *        All threads which are decendants of the context "server".
+ *
+ * The contexts are assumed to be placed in a tree. Each context has zero
+ * or one parent. If it has zero parents it is a child of the root of the
+ * tree.
+ *
+ * A query consists of a sequence of parts separated by "/". This
+ * sequence specifies a path through the context tree. A context matches
+ * the query if the last part of the query matches the properties of the
+ * context and the parent of the context matches the query excluding the
+ * last part. The properties of a context matches a part if each property
+ * specified in the part matches the property of the same name in the
+ * context or if the name of the context matches the string specified in
+ * the part. There are also two wild cards. The part "*" matches any
+ * context. The part "**" matches any sequence of contexts. If the query
+ * starts with a "/" the first part of the query must match a child of
+ * the root of the context tree.
