/pulsar/crosscorr/combine_crosscorr_toplists.py : fixed a bug cause losing 1 candidate in each toplist
/pulsar/crosscorr/combine_crosscorr_toplists.py: reverted a stupid mistake in combine toplist script due to misreading
/pulsar/crosscorr/combine_crosscorr_toplists.py: fixed several index in function
Added COMPLEX16Vector to the allowed data types in LALInference, and added a REAL8TimeSeries of data variance values to the LALInferenceIFOData structure
 - closes #1721
pulsar_parameter_estimation_nested: some major changes to speed up the code and allow a Gaussian likelihood to be used
 - in cases where the algorithm is not searching over parameters that vary the signal
   phase evolution the antenna pattern a(t) and b(t) functions are pre-summed before
   the model and likelihood evaluation
 - if the input data has four columns, with the last being the noise standard deviation,
   then a Gaussian likelihood will be used. A Gaussian likelihood can also be specified
   on the command line for data where no standard deviation is included, where in this
   case the variance will be calculated from running median substracted data.
Added pre-summing of models for all non-GR components (still need to add this to the SNR calculation code though)
pulsar_parameter_estimation_nested: code with non-GR options and speed up likelihood calculation now compiles

Fixed a couple of bugs
pulsar_parameter_estimation_nested: functions have been split into separate files
pulsar_parameter_estimation_nested: initialised some unintialised variables that were breaking the build
lsctables: remove redundant numpy imports inside functions
LALInferenceBAMBI.c:  print logZerr and logZnoise in addition to logZ in [root]evidence.dat file
