TCRT_Test should be working as expected

CrowdSource and FieldTest_File:
- after getting the absolute path of the file passed, we remove the
back slashes

FieldTest_File:
- hack to let me test the sample file with traceroutes

TCRT_Test:
- Ping class now has a boolean _Timeout.
- Ping class __str__ function now defined
- Hop class now parses its given line.
- Hop class __str__ and get_RTTsAsArray() functions now defined
- TCRT_Test class gathers some extra info from the string passed to
__init__
- TCRT_Test has a get_RTTsAsArray function, as well as a
get_AvgRTTAsArray function. get_RTTs returns a two-dimensional array of
floats, while get_AvgRTT returns a one-dimensional array of floats
- TCRT_Test __str__ function defined.
