Changelog for SourceGraph-0.5.2.0

Changes since 0.5.2.0 ===================== * Shift overall analysis to the top and per-module analysis to the end, as suggested by Duncan Coutts. * Graph drawing fixups: instances are now drawn correctly, and the module graph now has modules located in the correct directory. * Improve some graph drawing aspects (node margins, colours for module graphs, etc.). Changes since 0.5.1.0 ===================== * Add support for passing a single Haskell source file rather than a Cabal file as the argument, as requested by Curt Sampson. * Shade backgrounds of modules when clustering Entities. * RelativeNeighbourhood doesn't provide good alternate modules and takes up too much runtime, and so has been removed. Changes since 0.5.0.0 ===================== * Re-write of parsing. * Usage of new graphviz and Graphalyze features. * More abstraction into common routines into Analyse.Utils
