Provides a hash table-like interface to a fixed-sized array that has a constant key size and record size:
require Tie::SubstrHash; tie %myhash, "Tie::SubstrHash", key_len, value_len, table_size;
To tie a new hash to this package, specify the following:
key_len Length of each key
value_len Length of each value
table_size Size of the table given as the number of key/value pairs
An attempt to store a key/value pair in which either the key or the value is the wrong length, or in which the resulting table would be greater than table_size, results in a fatal error.
