Simple Structured Data Format (SSDF)

The Simple Structured Data Format (SSDF), is a format for storing structured (scientific) data.

The goal of the format is to be easily readable by humans as well as computers. It is aimed for use in interpreted languages like Python or Matlab, but it can be used in any language that supports the seven datatypes listed below.

Elements in a data structure can be one of seven different data elements, of which the first two are a container element (which can be nested):
* dictionary (an ssdf.Struct object in Python)
* list (of elements with no name)
* (Unicode) string
* float scalar
* int scalar
* (numpy) array of any type and shape
* Null (None)

SSDF has similar goals as JSON, but also enables (relatively) efficient storing of binary data and is much easier to read.
