some Questions

[PhilipDeegan]

Hi there,

This is really nice, thanks for making it available.

I have it running on fedora and debian with some minor changes.

It seems in the current version of PCL there is a compile error as an undefined function is being used pcl::getMaxDistance

Would you accept a pull request to rectify this by adding the include #include <pcl/common/common.h> in src/file.cpp?

Also, it would be nice to be able to override the define macro PATH_TO_SHADERS without having to edit src/shader.h, could a change be considered to ifdef it and default it to the current value?

thanks
