// Memory pool
//! This class is used by the parser to create new nodes and attributes, without overheads of dynamic memory allocation.
//! In most cases, you will not need to use this class directly.
//! However, if you need to create nodes manually or modify names/values of nodes,
//! you are encouraged to use memory_pool of relevant xml_document to allocate the memory.
//! Not only is this faster than allocating them by using <code>new</code> operator,
//! but also their lifetime will be tied to the lifetime of document,
//! possibly simplyfing memory management.
//! <br><br>
//! Call allocate_node() or allocate_attribute() functions to obtain new nodes or attributes from the pool.
//! You can also call allocate_string() function to allocate strings.
//! Such strings can then be used as names or values of nodes without worrying about their lifetime.
//! Note that there is no <code>free()</code> function -- all allocations are freed at once when clear() function is
//! called, or when the pool is destroyed. <br><br> It is also possible to create a standalone memory_pool, and use it
//! to allocate nodes, whose lifetime will not be tied to any document.
//! <br><br>
//! Pool maintains <code>RAPIDXML_STATIC_POOL_SIZE</code> bytes of statically allocated memory.
//! Until static memory is exhausted, no dynamic memory allocations are done.
//! When static memory is exhausted, pool allocates additional blocks of memory of size
//! <code>RAPIDXML_DYNAMIC_POOL_SIZE</code> each, by using global <code>new[]</code> and <code>delete[]</code>
//! operators. This behaviour can be changed by setting custom allocation routines. Use set_allocator() function to set
//! them. <br><br> Allocations for nodes, attributes and strings are aligned at <code>RAPIDXML_ALIGNMENT</code> bytes.
//! This value defaults to the size of pointer on target architecture.
//! <br><br>
//! To obtain absolutely top performance from the parser,
//! it is important that all nodes are allocated from a single, contiguous block of memory.
//! Otherwise, cache misses when jumping between two (or more) disjoint blocks of memory can slow down parsing quite
//! considerably. If required, you can tweak <code>RAPIDXML_STATIC_POOL_SIZE</code>,
//! <code>RAPIDXML_DYNAMIC_POOL_SIZE</code> and <code>RAPIDXML_ALIGNMENT</code> to obtain best wasted memory to
//! performance compromise. To do it, define their values before rapidxml.hpp file is included. \param Ch Character type
