annotate +sbp/Variable.m @ 99:ecf77a50d4fe feature/arclen-param

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
The arclength parameter function was slow because it called fzero. Now it is constructed once and for all with splines. Much better performance.
