Passing the zserver path via define

Instead of been a fixed path, I am passing the path for the zmq
server as a compiler argument.
Undefined variable in lambda

Clang is complaining about a possible undefined variable when using
closures.
Missing header

Clang is complaining about a class that cannot be found. Added the
header where the class is defined.
Invalid conversion from integer to string

There is no valid integer conversion to ostream. Using the std::string
to convert the integer to string before calling the operator <<.
Clang complaining about default argument.

For some strange reason, clang is complaining about the default
std::vector argument. I just overloaded the method with and without
the std::vector parameter.
Clang complaining about types

1- Casting the float to integer because clang was complaining about
   the type
2- For some reason, the UUID in my machine is longer than the one from
   the current test. I just add another check to validate it according
   the string size.
Passing the csv file location as arg

Instead of having the csv file location fixed in the code, I am
passing the location as compiler parameter.
Clang complaining about class definition

Clang was complaining about the class definition inside a lambda.
I changed the definition to be outside the lambda.
Changed the builtin function to be a std function

Replaced a __builtin_isxdigit function by a cctype isxdigit function
Variable length array of non-POD

Clang does not support variable length for non POD. Changed the code
to use a vector instead of an array if the compiler is clang.
Added BASE_DIR for tests

Tests are now supporting a BASE_DIR define, that will tell to the
project the absolute application directory location.
Use std::tuple instead of boost::tuple

Undefining the tuple definition to tell to boost to use the std::tuple
instead of boost::tuple
Clang complaining about const

1- Clang is much less permissive in regards to const. Changed the function
   pointers attribution to cast the const pointers to be non const.

2- Changed the exception to use exception_setter.
Curlpp macro redefined

Clang is complaining about the autotools macro redefinition in the
curlpp config.h. This is because autotools automatically creates
some macros for each project managed by it.

There is no way to turn off the warning using -Wno- argumento, so
I am undefining the macros directly in the code.
Invalid unittest check.

The unittest is checking for size == 8 but it should be == 3
