0.4.0.0: cleaning output and other tweaks

Release 0.4.0.0 sees a few changes:

• Added a --full-version flag to the executable, which includes which version of pandoc/pandoc-types was used, as well as the git revision.
• Added the clean command to the executable. This can be used to clean-up output files produced by pandoc-plot.
• Added the top-level function cleanOutputDir to clean output of pandoc-plot. This is only accessible if pandoc-plot is used as a library.

There is one small breaking change:

• Changed the flag --write-example-config to the command write-example-config. This creates a distinction between commands (which can perform IO operations), and command-line flags, which cannot.

Less important changes:

• Updated documentation.
• Added a distinction between failure to render a figure because of a mistake, and failing to render a figure because the toolkit is not installed. pandoc-plot will give better error messages in the latter case.

Caption formatting

This release sees one major change: caption formatting can now be specified in configuration files .pandoc-plot.yml. Parsing captions based on source file was not working. This unfortunately changes the type signature of a few high-level functions.

The default caption format is "markdown+tex_math_dollars".

Bug fixes and linux executables

This release sees two major changes:

• Linux executables are now available.
• Paths with spaces were not handled by a few toolkits (issue #2) . This has been fixed.

Initial installers and executables

This release includes the first Windows installer, as well as executable for Windows and Linux.

The supported toolkits are:

• Matplotlib
• Plotly/Python
• MATLAB
• ggplot2
• GNU Octave
• gnuplot
• Mathematica (untested)
