Uses the concurrent double-cube and single cube divisor extraction procedure.
Modifies the network in the end, after extracting all nodes. Note that
Ntk_NetworkSweep() may increase the performance of this procedure because
the single-literal nodes will not be created in the sparse matrix. Returns 1
if the network has been changed.]

Synopsis [Performs fast_extract on a set of covers.]
Description [All the covers are given in the array p->ppCovers.
The resulting covers are returned in the array p->ppCoversNew.
The number of entries in both cover arrays is equal to the number
of all values in the current nodes plus the max expected number
of extracted nodes (p->nValuesCi + p->nValuesInt + p->nValuesExtMax).
The first p->nValuesCi entries, corresponding to the CI nodes, are NULL.
The next p->nValuesInt entries, corresponding to the int nodes, are covers
from which the divisors are extracted. The last p->nValuesExtMax entries
are reserved for the new covers to be extracted. The number of extracted
covers is returned. This number does not exceed the given number (p->nNodesExt).
Two other things are important for the correct operation of this procedure:
(1) The input covers should be SCC-free. (2) The literal array (pCover->pLits)
is allocated in each cover. The i-th entry in the literal array of a cover
is the number of the cover in the array p->ppCovers, which represents this
literal (variable value) in the given cover.]

/*
Here is an informal description of the FX data structure.
(1) The sparse matrix is filled with literals, associated with
cubes (row) and variables (columns). The matrix contains
all the cubes of all the nodes in the network.
(2) A cube is associated with
(a) its literals in the matrix,
(b) the output variable of the node, to which this cube belongs,
(3) A variable is associated with
(a) its literals in the matrix and
(b) the list of cube pairs in the cover, for which it is the output
(4) A cube pair is associated with two cubes and contains the counters
of literals in the base and in the cubes without the base
(5) A double-cube divisor is associated with list of all cube pairs
that produce it and its current weight (which is updated automatically
each time a new pair is added or an old pair is removed).
(6) A single-cube divisor is associated the pair of variables.
