comment What is higher dimensional algebra?
One should also mention Charles Ehresmann. See my article discussing three themes in his work: groupoids, local-to-global,higher dimensions: arxiv.org/abs/math/0602499

comment computing homotopy type
The following answer may be relevant: mathoverflow.net/questions/51091/computing-homotopies/… . But 2-dimensional rewriting is probably not algorithmically solvable. On the other hand, J.H.C. Whitehead's ideas on Simple Homotopy Theory (SHT) were thought up in terms of generalising to higher dimensions Tietze transformations in group theory. The notions in SHT of expansions and collapses give possible connections with the combinatorial use of "shellability".
