<p>Synopsis [Definition of a literal]</p>
<p>Description [A literal is a variable with phase. Two thing determing a lteral: it's "sign", and the variable index. One bit is used to mark it's sign. 0->positive, 1->negative.</p>
<p>For every clause with literal count larger than 1, there are two special literals which are designated ht_literal (stands for head/tail literal to imitate SATO) It is specially marked with 2 bits: 00->not ht; dir = 1; or dir = -1; 10 is not valid. Each literal is represented by a 32 bit integer, with one bit representing it's phase and 2 bits indicate h/t property.</p>
<p>All the literals are collected in a storage space called literal pool. An element in a literal pool can be a literal or special spacing element to indicate the termination of a clause. The spacing element has negative value of the clause index.]</p>
