* to enable the user to setup their own functions for lwalloc/lwfree. Hence when being called
* from PostGIS we can ensure we use palloc/pfree for all memory requests rather than the
* system memory management calls.
*
* Since using the standard malloc/free is likely to be a common option, liblwgeom contains a
* function called lwgeom_install_default_allocators() which sets this up for you. Hence most
* people will only ever need this line within their lwgeom_init_allocations() function.
