alec.turner a424394109 Build modified streamline images
The official image from streamline does not currently work for the arm64
platform. As a temporary measure, the source code and docker build scripts
have been lifted from the official images and are used to build locally.

Some additional modifications are made to reduce overall image size, these
are documented in docker/README.md

/**
* It can sometimes be useful to get the average of data in an API result set,
* be it from a column, or a collection of cells. This method provides exactly
* that ability.
*
* @name average()
* @summary Average the values in a data set.
* @author [Allan Jardine](http://sprymedia.co.uk)
* @requires DataTables 1.10+
*
* @returns {Number} Calculated average
*
* @example
* // Average a column
* var table = $('#example').DataTable();
* table.column( 3 ).data().average();
*
* @example
* // Average two cells
* var table = $('#example').DataTable();
* table.cells( 0, [3,4] ).data().average();
