This commit just includes a few plans and a massive derrangement
of the fx module before it is to be refactored into the Timeline
module. The basic methods are included, but everything is broken

make `at()` method of morphable objects throw when no destination is set (#797)

Since gbox is completely replaced by rbox, we don't need
it anymore. There were also a few small errors to fix.

This commit fixes a number of issues with transformations:
- Removed move/dmove/etc... on groups
- Sugar was being passed origin instead of ox, oy
- Updated the changelog
- Removed parseMatrix in favor of new SVG.Matrix()
- .matrix is the getter for a matrix, not .transform
- added a [02:24:41] Using gulpfile ~/Desktop/svg/svg.js/gulpfile.js
[02:24:41] Starting 'lint'...
[02:24:43] Finished 'lint' after 2.32 s directive

This commit fixes all of the tests to reflect all of the changes to
our transform code. It also makes the default test output dots
instead of anything else.

This commit adds matrix composition and decompositions (untested),
it also adds another playground to test that this is working as
expected in every case.

We also fixed a few linting errors.

This commit modifies the specification (and in some places the code) to
reflect the changes to the transformations.

make ungroup working on groups and nested for one depths

This commit implements the new transformation model, but it also
needs to modify a few tests to fit the new format. This is still
a work in progress.

merge SVG.Doc and SVG.Nested. Add isRoot() method

proposal for #807, includes #550, `SVG.off()` multiple events and option argument

This commit updates the README with up to date instructions about
how to run and build the library, as well as how to run the tests,
playgrounds and performance tests

This commit adds playgrounds and a build:dev mode. Now you
can call npm run build:dev to make the linter warn you about
errors without breaking. Also, we now have playgrounds, where
you can use a built version of svg.js to run your own tests.

I added the linter here to make programming and running the tests
easier throughout the programming process.

Added the standard linter

This commit fixes a few typesetting issues that probably resulted
from the automated linting process

This commit completes the compliance of our code with the standard
linter. It is now building correctly and error messages are displayed
when somebody tries to build bad code!

This commit fixes most of the errors raised by standard.
There is still a strange call error, but that will be the
focus of the next commit

This commit completes the rest of the files, making sure they are
in the standard linting format. Next we will add the linter to
the build process of our application.

This commit reformats the code so that it complies with the
standard linting style. Its currently a work in progress, but
it is meant to pave the way for linting in the build process

This commit applies matrix operations to the current matrix, so
calling mat.rotate will rotate the current matrix directly

This commit allows us to form a compounded matrix by setting
parameters like scale, translate, rotate etc directly in a single
call by asserting a particular matrix order.

This commit simply identifies some of the code that we will be
retiring in 3.0.0 related to transformations. I have commented
and in some cases removed code that will not be required.

Changes
=======
- Added the new affine composition and decomposition functions
- Commented out code that will be removed in coming commits
