Template Dynamic array class that creates an array that can be used like a list or an array.
It grows and shrinks dynamically, while elements can be accessed via index. It is performance tuned for simple types like float etc. and for hi-level objects only stores pointers, which are not automagically SG_REF'd/deleted.
