Compatibility python2.6

Closes #35

See merge request !37

Now compatible with python2.6

Also tested with matplotlib < 143 test203 fail
because in that version the function set_xlim was not
yet existing.

All version of matplotlib < 143 are not considered as stable
therefore not supported.

I add a message in __init__

I also corrected a bug I added in a former commit:
  I prevent myplotlib.__init__ from importing tests
  but just testList.

This prevented `python myplotlib --test <test name>` to work
because no tests were in myplotlib.__dict__

So I change the import from:
from . import __dict__
to
from .test import __dict__

Now `python myplotlib --test <test name>` works

In MyAxes.update we wrote some inline loops
that are not compatible with python2.6

I just wrote them in not inline mode, it shoudl work

Macosx backend

added axColorbar

test203 failing: error unknown maybe due to matplotlib old version (1.3)

 mac backend test

test203 tests Axes constructor with direct keywords
test204 tests Axes.update function

also changed the way myplotlib import tests

Closes #32

inlined looping, and make use of matplotlib.axes.update function

see issue 32 - in short matplotlib is a ****

new suggestion on MyFig.update().

See merge request !27

Update README

See merge request !29

Version numbers update?

See merge request !28

now can use in mytool module

	usage()
or
	usage(<fct-name'>)

(this time with changes)

MyAxes.update() allows to write the MyFig.update() shorter and clearer. I vote to make use of that.

Add specific config

See merge request !26

be stored.

Added one for newton, since GTKAgg is the only one that work
and latex is not supported because of dvipng not installed.

in case matplotlib has a version number with more than 3 numbers
like on newton (0.99.1.1) the former version gave: 9911 that is larger than 150...
eventhough 0.99 is older than 1.5

I correct by comparing only the 3 first numbers: now return 99 < 150

On the way to v3
