  A demonstration of the PcSet to Svg capability. You can build the svg
  files in this directory using 'make svg'.


Simplest case: a standard, well known pitch class set -- now featuring an
inversion axis.

> import qualified Data.PcSets as P
> import qualified Data.PcSets.Svg as S

The C Major Scale is a standard pitch class set: seven tones in 12-TET
(modulus 12). If the C Major set is inverted about the axis containing
pitch 2, the resulting set has the same elements. It's easier to see this
with a diagram -- which is the purpose of this module!

> cMajor :: P.StdSet
> cMajor = P.stdset [0,2,4,5,7,9,11]

The Data.PcSets.Svg module generates the *contents* of the .svg file as a
string. It's up to you to print this string to stdout or save it as a file
directly.

Here I'm adding the 'invertXY 2 2' axis. This could also have been entered
as (0,4), (4,0), (5,11), or any number of other specifications for pitches
that exchange in the operation.

> main :: IO ()
> main = putStrLn $ S.pcSvgAx cMajor (2,2)
