small cleanup in W+jets with central qqbar

simplified code for jWuno contraction

Updated confusing caption

Merge branch 'PureCentralQQX' into 'master'

Prefer `++x` to `x++`

Perform contractions. Reduce nested for loops from 4->2

use `c++11` list initialisation

Use `HEJ::metric()`

Use const where possible in current impl

Add regression test for PureCenQQx XS

Additional placeholder ME tests for Pure Jet CentralQQx.

Central QQX Implemented. Update Classification tests

Added `tree_kin_jets_qqxmid` which calls ME_qqxmid..` level function

Added `ME_qqxmid_current()` function which calls HEJ ME

Added call for CentralQQx in Pure Jets

Remove Tabs

Removed Unused variables. (Compiler warnings)

ME copied from HEJ1

Anonymous namespace + Identations

Line Length + Header Declaration

Remove Dead Code

Add XS test for Pure Extremal qqx

remove unnecessary variables in calc of `void eps()`

utilise standard library

Removed colour factor of "1/4(N_C^2-1)" from explicit ME calc (and update CI…

Utilise Anonymous Namespace

Improve efficiency of ExQQx calc (less nested for loops)

Use `HEJ::metric()`. Reduce for loops. Visuals. More const.

Todos, visuals and prefer `++x` to `x++`

Remove superfluous code

C++11 Initialisation. Visuals. Remove unnecessary argument

Remove unnecessary bool, use const.

Merge branch 'master' of gitlab.dur.scotgrid.ac.uk:hej/HEJ into CrossUnoPure…

Fix: CAM Factor removed. See HEJ_Explorer commit: hej_explorer@d2110e23.

Updated CI test after bug fix

More const by use of `()?():()` operator.

Removed TODO. Indentations

Protect joi/joo from negative energies introduced by crossing.

Remove superfluous if's. Variables const where possible

Indentation

Prefer `std::abs()` over `abs()`

Lesson: `std::abs()` much better behaved than `abs()` using `abs` on eg `pout.

Updated Classify tests to reflect Extremal qqx in Pure.

Cut down long lines (To pass `No_Tabs` test)

Remove Unused `void j()` function

Merge branch 'master' of gitlab.dur.scotgrid.ac.uk:hej/HEJ into PureExqqx

ExtremalQQx now claassified as "resummable" for Pure Jets

Remove Dead code + Correct Indentation

Fix: j() not the same as joi()

Updated CI test for Pure Subleading.

Remove dependence on void j()

Added Subleading ME test for Pure Jets. FAILS. (Negative Energy, nan)

Port Old Currents Across

Added reference to the Extremal qqbar Pure Jets in dev manual

Added Extremal qqbar (Pure Jets) reference to Change Log

Added calls for ExQQx forward and backwards

Moved assert one function up to avoid Unused parameter compiler warning.

Added function declarations for Pure ExQQx

Removed dead code + added missing doxygen declaration
