Allocate An Array and Call Default Constructor for its Elements

Syntax
array = thread_alloc::create_array<Type>(size_min, size_out) .

Purpose
Create a new raw array using thread_alloc memory allocator (works well in a multi-threading environment) and call default constructor for each element.

Type
The type of the elements of the array.

size_min
This argument has prototype
    size_t size_min
 This is the minimum number of elements that there can be in the resulting array .

size_out
This argument has prototype
    size_t& size_out
 The input value of this argument does not matter. Upon return, it is the actual number of elements in array (  size_min <= size_out ).

array
The return value array has prototype
    Type* array
 It is array with size_out elements. The default constructor for Type is used to initialize the elements of array . Note that delete_array should be used to destroy the array when it is no longer needed.

Delta
The amount of memory inuse by the current thread, will increase delta where
    sizeof(Type) * (size_out + 1) > delta >= sizeof(Type) * size_out
 The available memory will decrease by delta , (and the allocation will be faster) if a previous allocation with size_min between its current value and size_out is available.

Alignment
We call a memory allocation aligned if the address is a multiple of the number of bytes in a size_t value. If the system new allocator is aligned, then array pointer is also aligned.
