[ojAlgo-user] ANN v12

[Anders P. <ap...@op...>]

Main changes:

1) ArbitraryArray has been renamed BasicArray to better comply with the 
ojAlgo naming standard (that I may document some time in the future). A 
temporary/deprecated interface called ArbitraryArray remains.

2: PhysicalStore no longer extends BasicArray (ArbitraryArray). This 
will make it more straight forward to implement other kinds of 
PhysicalStore in the future (sparse stores).

3: BigFunction, PrimitiveFunction & ComplexFunction have been "cleaned" 
and moved to its own package org.ojalgo.function.implementation. Stuff 
that didn't fit among the new clean contents moved to org.ojalgo.MathUtils.
