Implements some basic array storage allocation functions.
This class isn't really for public use - it used to be part of the container classes but has since been superseded by ArrayBase. Eventually it will be removed from the API.

Increases the amount of storage allocated if it is less than a given amount.
This will retain any data currently held in the array, but will add extra space at the end to make sure there it's at least as big as the size passed in. If it's already bigger, no action is taken.
minNumElements | the minimum number of elements that are needed |
