v0.6.0-alpha

The structure of the package was changed to improve the code organization. A few modules have been split into smaller ones, and functions have been separated into three main groups: communications (comm), physical models (models), and digital signal processing (dsp). Each group will have subgroups of modules gathering functions with similar applications. For example, before we had

from optic.models import edfa, ssfm
from optic.dsp import cpr, edc
from optic.modulation import modulateGray
from optic.metrics import monteCarloGMI

and now it should be from optic.models.amplification import edfa

from optic.models.amplification import edfa
from optic.models.channels import ssfm
from optic.dsp.carrierRecovery import cpr
from optic.dsp.equalization import edc
from optic.comm.modulation import modulateGray
from optic.comm.metrics import monteCarloGMI

The documentation has been improved.
