annotate test/Grids/EquidistantGrid_test.jl @ 877:dd2ab001a7b6 feature/equidistant_grid/refine

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Implement refine function, move exports to the top of the file, change location of constuctors. The constructors were changed have only one inner constructor and simpler outer constructors.
