MStorage - simple multi-type map storage for some fixed data types

Absolutely no warranty. Use at your own risk. Written for one small game.

Supported types:

• 32-bit Signed Integer
• 32-bit Signed Integer Array
• 8-bit Unsigned Integer (Byte)
• 8-bit Unsigned Integer (Byte) Array
• Double
• String (std::string)

Features:

• Values and groups are associated with keys.
• Grouping. All of types listed above can be grouped.
• Base types are casted automatically to each other.
• Writing to file / reading from file.
• Writing and reading from stream.

Example usage:

Assigning and writing to file:

    MStorage mst;
    mst.setInt("someInt", 123456);
    mst.writeToFile("data.mst");

Reading:

    MStorage mst;
    mst.readFromFile("data.mst");
    int32_t val = mst.getInt("someInt");   

Groups:

    MStorage mst;
    MStorage *group = new MStorage();
    group->setString("str", "Hello");
    mst.setGroup("someGroup", group);  
 
    std::string str = mst.getGroup("someGroup")->getString("str");

Iterating:

    MValueMapIterator it = mst.begin();
    while(it != mst.end()) {
        MStorageBase *val = it->second;
        // do something
        // type can be discovered via val->getType()
        it++;
    }
