//Water_csplines.cc - Basic, non-interactive module for handling water mediums. Uses a csplines generated from a lookup table for mass attenutation coefficients.
//
//Programming notes:
// -Do not make items here "const", because they will not show up when loading.
// -Avoid using macro variables here because they will be obliterated during loading.
// -Wrap dynamically-loaded code with extern "C", otherwise C++ compilation will mangle function names, etc.
//
// From man page for dlsym/dlopen: For running some 'initialization' code prior to finishing loading:
// "Instead, libraries should export routines using the __attribute__((constructor)) and __attribute__((destructor)) function attributes. See the gcc 50.0o pages for
// 50.0ormation on these. Constructor routines are executed before dlopen() returns, and destructor routines are executed before dlclose() returns."
// ---for instance, we can use this to seed a random number generator with a random seed. However, in order to pass in a specific seed (and pass that seed to the library)
// we need to define an explicitly callable initialization function. In general, these libraries should have both so that we can quickly adjust behaviour if desired.
