Added outer_boundary_corners property to the area def class
More active support of swath to swath reprojection
Removed debug printouts
A stray line of code is removed and I take back the recent enhancement concerning swath to swath mapping.
Add a plot on multiprocessing performance increases.

[travis] added system dependencies

 * matplotlib requires libfreetype6-dev
 * basemap requires libgeos libgeos-c1 and libgeos-dev
[setup] added plotting dependencies

pyresample/plot requires two extra dependencies:
 * matplotlib
 * basemap
Added more meaningful "quicklooks" name

Using quicklooks name as it's what matplotlib and basemap are needed for
Install extra requirements using pip functionality
Using ubuntu GIS custom ppa

Added custom ppa with more up-to-date libgeos dependencies
don't use setup.py for basemap installation

Instead of putting basemap and matplotlib into `extras_require`
install them directly

Merge branch 'master' of github.com:mitkin/pyresample
remove pip `-e` switch
[README] markdown + build status

 * Using markdown extension, added `README` symlink
 * Added travis build status badge
[pip+travis] use `requirements.txt`

Use `requirements.txt` instead of setuptools' `extras_require`
for installing basemap.

That is because PyPi basemap version won't find libgeos library
so we resolve to use latest basemap from git. `Extras_require` don't
allow providing custom links, only PyPi package names, so we have to
specify links in requirements.txt. `dependency_links` argument to
`setup` call is meant for cruicial dependencies, not custom ones, so we
don't use them neither.
[test_plot] allow travis to test plot.py
