Mostly formatting changes. Important issues first

NEW:
TCRT_Test:
This is a trace route test object. It will work similar to the PING
tests, as the information gathered is quite similar.
- code is all PING_Test’s code

_Measurement:
- now contains the Final_Measurement class, and UDP_ServerReport class.
Files have been deleted. imports now run as such. “from
iperf_output._Measurement import Final_Measurement”

_File:
- added function for finding and passing text to TCRT_Test constructor
- added key value “TCRT” to self.Tests
- When appending parsedTest objects (TCP_Tests, PING_Tests, etc.), the
key used is now parsedTest.ConnectionType (as this should be the
correct string)

ALL OTHER FILES
- simply documentation formatting
