=head1 DESCRIPTION
=begin comment
POD is pretty good at recognising function names and making them appropriately
bold... however, when part of the function name is variable, we have to help
the processor along
=end comment
SPARSE_ARRAY_OF() returns the name for a sparse array of the specified
B<TYPE>. DEFINE_STACK_OF() creates set of functions for a sparse array of
B<TYPE>. This will mean that a pointer to type B<TYPE> is stored in each
element of a sparse array, the type is referenced by SPARSE_ARRAY_OF(TYPE) and
each function name begins with I<ossl_sa_TYPE_>. For example:
B<I<TYPE>>. DEFINE_STACK_OF() creates set of functions for a sparse
array of B<I<TYPE>>. This will mean that a pointer to type B<I<TYPE>>
is stored in each element of a sparse array, the type is referenced by
B<SPARSE_ARRAY_OF>(B<I<TYPE>>) and each function name begins with
B<ossl_sa_I<TYPE>_>. For example:
TYPE *ossl_sa_TYPE_get(SPARSE_ARRAY_OF(TYPE) *sa, ossl_uintmax_t idx);
ossl_sa_TYPE_num() returns the number of elements in B<sa> or 0 if B<sa> is
B<NULL>.
B<ossl_sa_I<TYPE>_num>() returns the number of elements in I<sa> or 0 if I<sa>
is NULL.
ossl_sa_TYPE_get() returns element B<idx> in B<sa>, where B<idx> starts at
zero. If B<idx> refers to a value that has not been set then B<NULL> is
B<ossl_sa_I<TYPE>_get>() returns element I<idx> in I<sa>, where I<idx> starts

B<ossl_sa_I<TYPE>_set>() sets element I<idx> in I<sa> to I<value>, where I<idx>

ossl_sa_TYPE_new() allocates a new empty sparse array.
B<ossl_sa_I<TYPE>_new>() allocates a new empty sparse array.
ossl_sa_TYPE_free() frees up the B<sa> structure. It does B<not> free up any
