TestApp is throwing attribute error

[draperjames]

When I run TestApp.py I recieve the following error;

C:\Anaconda3\lib\site-packages\qtpandas\encoding.py:21: UserWarning: Detector.Issues importing libmagic - got an error: [WinError 193] %1 is not a valid Win32 application
  warnings.warn("Detector.Issues importing libmagic - got an error: {}".format(e))
Error in sys.excepthook:

    tbinfo = tbinfo.decode('utf-8')

Original exception was:

I think we need to change decode to encode. It should be compatible with py2/3

Okay I swapped decode for encode and here is the error message that I get now;

C:\Anaconda3\lib\site-packages\qtpandas\encoding.py:21: UserWarning: Detector.Issues importing libmagic - got an error: [WinError 193] %1 is not a valid Win32 application

I opened this PR#19 to solve the issue and I'll merge the branch when I have it sorted. @zbarge have you had any problems with this? Are you using python2 at all? I think we need to update the .travis.yml file to actually test things correctly b/c right now the thing passes if the project builds.

[zbarge]

Kinda looks like different errors between the two comments. The first is

OSError: File b'C:\Users\Lenovo\AppData\Local\atom\app-1.12.6\testData/test1.csv' does not exist

The next one looks like it could be because the filepath string is formatted as a bytes string instead of a regular (or raw) string. I'll take a look now.

Actually I meant to close this. With #20.
