`record_info_runtime` `Parse Transform`

=======================================

Provides the functions:

    record_info_size/1

    record_info_fields/1

Which are the runtime equivalent of:

    record_info(size, _)

    record_info(fields, _)

The complete list of functions provided by the parse transform for

runtime usage with a variable storing the atom record name is below:

* `records/0` - List of all record names defined

* `record_new/1` - Create a record with the defaults assigned

* `record_info_size/1` - Provide the record size (same as `erlang:tuple_size/1`)

* `record_info_fields/1` - Provide the record fields list (atom names for each record field)

* `record_info_fieldtypes/1` - Provide the record fields paired with their types in a list of tuples
