Detailed Description

template<typename X>
class ArrayOf< X >

Memory.h template class for making an array of float, bool, etc.

This simplifies arrays of arrays, each array separately allocated with NEW[] But it might be better to use std::Array<ArrayOf<X>, N> for some small constant N Or use just one array when sub-arrays have a common size and are not large.
