Detailed Description

Maintain a collection of TTValue objects indexed by TTSymbol pointers.

The TTValue objects can themselves include TTSymbol pointers, TTObjects, simple values, polymorphic arrays, etc.

TTHash is implemented as a light wrapper class around the STL hash_map templates. While we could inherit from hash_map and then override the appropriate things, there are a few reasons to just contain the hash_map and wrap it.

• For example, we may later make TTHash inherit from TTObject and want to address it with messages.
• This approach isolates coders from having to worry about an template craziness
• This approach offers the possibility, should the need ever arise, to change the underlying implementation away from STL.
