// https://github.com/jhawthorn/fzy/blob/master/src/match.c and
// https://github.com/jhawthorn/fzy/blob/master/ALGORITHM.md
// For a fuzzy match string needle being searched for in haystack we provide a
// number score for how well we match.
// We create two matrices of size needle_len (n) by haystack_len (m).
// The first matrix is the score matrix. Each position (i,j) within this matrix
// consists of the score that corresponds to the score that would be generated
// by matching the first i characters of the needle with the first j
// characters of the haystack. Gaps have a fixed penalty for having a gap along
// with a linear penalty for gap size (c.f. gotoh's algorithm).
// matches give a positive score, with a slight weight given to matches after
// certain special characters (i.e. the first character after a `/` will be
// "almost" consecutive but lower than an actual consecutive match).
// Our second matrix is our diagonal matrix where we store the best match
// that ends at a match. This allows us to calculate our gap penalties alongside
// our consecutive match scores.
// In addition, since we only rely on the current, and previous row of the
// matrices and we only want to compute the score, we only store those scores
// and reuse the previous rows (rather than storing the entire (n*m) matrix).
// In addition we've simplified some of the algorithm compared to fzy to
// improve legibility. (Can reimplement lookup tables later if wanted.)
// Also, the reference algorithm does not take into account case sensitivity
// which has been implemented here.
