Merge branch 'feature/finite-element-implementation-selection' into 'master'

ref:extensions/dune-codegen So far, we were a bit sloppy about which basis we
choose from the UFL counterpart. This commit implements the necessary 1-to-1
mapping.

This fixes [#146]

Merge branch 'feature/remove-rangefield-template-parameter' into 'master'

ref:extensions/dune-codegen In many places we treat this as codegen-time

Merge branch 'feature/more-codegen-time-evaluation' into 'master'

ref:extensions/dune-codegen (Partial) Evaluation of arithmetic expressions at
code generation time is a vital tool to generate minimal-FLOP code and a
genuine advantage of code generation. This MR adds evaluations for matrix
inverses, sums and products.

Merge branch 'feature/offline-usage' into 'master'

ref:extensions/dune-codegen @rhess Could you try this at some point.

The docs are currently missing how a local package index can be relocated into
a completely isolated environment, but I want to wait until the [devpi
website] is up again to read up on that.

This fixes [#127].

Merge branch 'feature/sde-performance-measuring' into 'master'

ref:extensions/dune-codegen This allows to use [Intel SDE] for performance
measurements. SDE is capable of counting exactly the executed FLOP and
transferred Byte of a program. The output is quite excessive, but it can be
reduced to the essentials with [this] script.

**Warning:** SDE increases the runtime considerably, it should only be used
for small problems.
