Compilation issue

Hi Andrew,

I'm getting compilation errors due to missing ceil and floor. My gcc 9.2.0 is quite new; maybe it is wrongly compiling the sources as C++14?

isolation.cpp: In function 'int main(int, char**)':
isolation.cpp:145:24: error: 'floor' was not declared in this scope
  145 |   for (int lat = (int) floor(bounds[0]); lat < (int) ceil(bounds[1]); ++lat) {
      |                        ^~~~~
isolation.cpp:145:54: error: 'ceil' was not declared in this scope; did you mean 'el'?
  145 |   for (int lat = (int) floor(bounds[0]); lat < (int) ceil(bounds[1]); ++lat) {
      |                                                      ^~~~
      |                                                      el

Interesting.. the makefile sets -std=c++11 and it built locally on a Mac. I've explicitly included <cmath> now. Let me know if that works. You can also send a PR if you find other build problems.

I've had already patched ceil/floor to std::ceil/floor, so probably this works.
