This is work to put data sources onto a more stable and robust footing.

The initial work is to make all the array-based data source classes inherit from a common, robust base class and to add abstract base classes for common required formats (sequences, images, etc.).

Fixes #247 and a number of other issues.

  • base class for array data sources
  • re-write current data sources to inherit from it
  • add appropriate new data sources that inherit from it (eg. color sequence for colored scatterplots, text sequence)
  • make AbstractDateSource a formal ABC.
  • add subclasses for sequences, Images, 2D Grids, etc.
  • write data sources for Pandas Series and Index types (possibly).
