 - Added a Poisson-disc sampling subpattern

+# Bugfix
 - Fixed bug with subpattern.enclosed which would generate more than one enclosed

-### Misc
+# Misc
 - Improved circle raster (no longer repeats points)
 - Integrated all tests into a single test script, and added luacov coverage
 - Converted subpattern.random to take as an argument a fixed integer number of
   desired samples rather than a fraction of the domain size.
 - Removed special handling of '-0' coordinate in cell: No longer required with
   integer spatial hash in patterns.
-- Made pattern coordinate limits explicit in MAX_COORDINATE
+- Made pattern coordinate limits explicit in `MAX_COORDINATE`
 - Changed internal structure of `pattern`, from a list of cells to a list of
   coordinate hashes
 - Various optimisations
 - Removed some (confusing) functionality from `cell`, namely addition and
   multiplication with a number value.
 - Added isoline drawing example
-- Renamed pretty_print to print_patterns
+- Renamed `pretty_print` to `print_patterns`

+# Bugfix
+- Fixed lazy initialisation through 'require ("forma")'

 # Misc
+- Improved pattern documentation
 - Greatly expanded test coverage
-- Slightly faster convergence check for automata.iterate
 - Slightly streamlined corridors example
-- Changed coordinate handling of pattern.new with prototype to match behaviour
-  from pattern:\_tostring
