3396	add a sparse_view class that wraps pre-allocated data into a matrix expression	Gunter	Gunter	"Provide a way to use ublas with pre-allocated data. Implement a matrix view of a CRS matrix as proof of concept. Details:

* given 3 arrays: row pointers, column indices, values (http://www.netlib.org/utk/papers/templates/node90.html)

* provide a wrapper that fulfills the immutable part of the matrix expression

Further tasks:

* split the current matrix and vector concepts into immutable and mutable parts in order to gain a ""read-only view"" concept and a full featured ""expression"" concept

* improve traits mechanism and apply it where possible to automatically see a fixed size C-array as vector view or matrix view

* add necessary tests
