+ * These variable types can efficiently store primitive data types such as
+ * integers, strings, binary string, booleans, floating point numbers,
+ * pointer references, and objects. EjsVars are the universal type used by
+ * EJ to hold objects, classes and properties.
+ * \n\n
+ * An EjsVar may store one of the following types:
+ * @li Boolean
+ * @li Floating point (if supported in this build)
+ * @li Integer
+ * @li 64 bit integer (if supported in this build)
+ * @li String
+ * @li Binary string
+ * @li C function or C++ method
+ * @li C function with string args
+ * @li Javascript method
+ * @li Object
+ * @li Null value.
+ * @li Undefined value
+ * \n\n
+ * Objects can hold object properties which are themselves EJS variables.
+ * Properties are hash indexed by the property name and are stored in
+ * an ordered sequence. i.e. Order of properties is maintained. Objects may
+ * be referenced by multiple variables and they use garbage collection to
+ * reclaim memory no longer in use by objects and properties.
+ *
+ * @warning This module is @e not thread safe for performance and
+ * compactness. It relies on upper modules to provide thread
+ * synchronization as required. The API provides primitives to get
+ * variable/object references or to get copies of variables which should
+ * help minimize required lock times.

+ * @overview This symbol table uses a fast key lookup mechanism. Keys are
+ * strings and the value entries are arbitrary pointers. The keys are
+ * hashed into a series of buckets which then have a chain of hash
+ * entries using the standard doubly linked list classes (List/Link).
+ * The chain in in collating sequence so search time through the chain
+ * is on average (N/hashSize)/2.
+ * @remarks This module is not thread-safe. It is the callers responsibility
+ * to perform all thread synchronization.
