Converter fix

In STDs, the function that converts the structure of StDev values into
a 2-D array now works correctly.
main.py also has a few small changes.
wrong function call fix
Working on calculating distrib of StDev

utils
- added StDevP function (I know it can be imported, but it was fun to
code)

STDs
- changing all of the value ranges into ints before extending (i.e.
printing in the 2D array). makes then easier to read

SpeedTestFile, Indiv, PingThread
- Working on getting the StDevs of the sums of the threads in one
direction. Running into some problems.
!!!! The above problems require some more work on the parsing of the
data files !!!!
Working on parsing errors that affect StDev

PingThread now has in-class attributes of final ping start, end, size,
and speed

IndivSpeedTest now removes empty threads (if error occurred while the
test was being done, leading to an empty thread)

In SpeedTestFile, no longer have to check for ping thread of length 0
before array_itizing
Fixed UDP error breaking the program

+Added error checking when creating UDP PingThreads.
+Corrected some bad logic when creating UDP PingThreads
(self.this_PingThreads[0] was 100% wrong and was adding pings to the
wrong PingThread)
+Created a test environment for the bad file
commenting out print
better condition for testing if file is netbook

Each netbook test file’s 2nd line does NOT have “Testing started”. This
is a better check than if the file name starts with “WBBDtest”
declare network type in date time test

this is best location to do this declaration, as it is when we know
what type the file falls into
