+/* Alignment represents an alignment object in a 2D format to support function word-based models calculation
+
+ A note about model's parameter estimation:
+ ==========================================
+ The model is estimated as a two-level Dirichlet process.
+ For orientation model, the first tier estimation is:
+ P(o|f,e) where *o* is the orientation value to estimate, *f* is the source function word aligned to *e*
+ its second tier is: P(o|f), while its third tier is P(o)
+ For dominance model, the first tier estimation is:
+ P(d|f1,f2,e1,e2) where *d* is a dominance value to estimate, *f1,f2* are the neighboring function words on the source
+ aligned to *e1,e2* on the target side
+ its second tier is: P(d|f1,f2) while its third tier is P(d)
+
+ Taking orientation model as a case in point, a two level estimation proceeds as follow:
+ P(o|f,e) = c(o,f,e) + alpha { c(o,f) + beta [ c (o) / c(.) ] }
+ ------------------------------
+ c(f) + beta
+ -------------------------------------------------
+ c(f,e) + alpha
+ where c() is a count function, alpha and beta are the concentration parameter
+ of the first and second Dirichlet process respectively
+ To encourage or penalize the use of second and third tier statistics, bo1 and bo2 binary features are introduced

+ 2. call *als->computeOrientationSource*, *als->computeOrientationTarget*,
+ *als->computeDominanceSource*, or *als->computeDominanceTarget*
+ and pass the resulting score to either *features* or to *estimated_features*
+ 3. call *als->BorderingSFWsOnly()* and *als->BorderingTFWsOnly()*, which removes records of all function word
+ alignments except those at the borders. Note that fw alignments kept may be more than two on each side
+ for examples if there are a number of unaligned fw alignments before the leftmost alignment or the rightmost one
+ 4. call *als->simplify()*, which assigns the state of this edge (*context*). It simplifies the alignment space to
+ its most compact representation, enough to compute the unscored models. This is done by observing the surviving
+ function word alignments set by 3.
