Fixed some data type issues with Cubic. Note: the '==' operator does not work with floating point values, as depending on the order of operations that generated the value, there can be tiny differences with values like '0.2'. Notice the change on lines 208-209.

OCD change on IP script.

Example in VTK doc
Added default values to stats_pores and stats_throats, so that test networks can be generated on the fly
Uncommented the Add 'coords' to boundaries code

Line 149 had to stay commented, as 'coords' was already appended with zeros.

It looks like it's working alright
Unbroke IP
Merge branch 'feature/James_misc_cleanup' into develop
