pep8-ify function names

[eric-wieser]

Following on from this comment.

So instead of

task.CfgSampClkTiming(
    source=None,
    rate=1,
    activeEdge=daq.Val_Rising,
    sampleMode=daq.Val_FiniteSamps,
    sampsPerChan=1
)

it would become

task.cfg_sample_clk_timing(
    source=None,
    rate=1,
    active_edge=PyDAQmx.VAL_RISING,
    sample_mode=PyDAQmx.VAL_FINITE_SAMPS,
    samps_per_chan=1
)

This potentially raises the issue that the module name should be PEP8'd as well, becoming the much easier to type pydaqmx

@clade's remark from that thread:

I hesitate to rename the function using the PEP8 for two reasons : the documentation is not available for Python but in C. The second reason is that functions are closer to C functions than to python functions. I have in mind to write real python function (for example to remove the byref and returns the value). In this case I will rename the function using the PEP8

Maybe for the next major release (v2.0.0), the package name should also be changed to pydaqmx for similar reasons.

[eric-wieser]

That needn't wait - the switch could be made right now, and a reasonably simple PyDAQmx.py containing from pydaqmx import * added, assuming __all__ doesn't interfere with things

The dev2 branch is a tentative to pep8-ify the package.

The setup.py should install two package : the main one (pydaqmx) and a legacy one (PyDAQmx) that depends on the first one.

Changing the name of the all the functions, constant and arguments was not easy so I have decided to completely change the structure of the package and to use object to create the functions.

You can see the functions and constants with the commands :

import pydaqmx
print pydaqmx.functions.__all__
print pydaqmx.constants.__all__
print pydaqmx.cfg_samp_clk_timing.__doc__

The dev2 branch is now tested.

For example :

with pydaqmx.Task() as t:
    t.create_ai_voltage_chan("dev1/ai0","",pydaqmx.VAL_CFG_DEFAULT,-10.0,10.0,pydaqmx.VAL_VOLTS,None)
